This is really weird... I found some references to event logs sometimes causing these issues, so I cleared out some of the event logs on the system and now the performance test when plugged in is similar to that when running on battery (I have both set to utilize the most system resources). I have no clue why this would be so...but it seems to be.

Have you adjusted the settings in Control Panel\All Control Panel Items\Power Options\Edit Plan Settings, Advance options, which have separate options for On battery and Plugged in? That is the most likely cause of the issue, particularly active vs. passive cooling in Processor power management. See 13 Ways to Save Power for more information, and Power ...

Designing a processor to deliver high performance is far more than just increasing the clock rate. There are numerous other ways to increase performance, enabled through Moore's law and instrumental to the design of modern processors. Clock rates can't increase indefinitely. At first glance, it may seem that a processor simply executes a stream of ...

There are two things that can limit performance among CPUs: the internal factors and the external factors. Basically the internal factors are what is intrinsic to the internal core architecture of the CPU. The first thing to note is the number of cycles per instruction your CPU requires. For example, on floating point operations it went from above 50 or 60 ...

CPU clock speed is only one of the many factors in "speed." Bus speed, memory speed, disk speed, instruction sets, cache, application design, etc, etc. All of these factors play a role in overall speed. Intel Atom CPUs are not designed for intense calculations. They are designed for low power computing. This is why they often do not have fans or ...

The clock speed provided by the specifications is the external clock speed, or data transfer rate to and from the CPU. In the Celeron and Atom CPUs, this is also the internal clock speed. For the i3, i5 and i7, the clock is multiplied to give a faster internal clock. The i7, with multiple cores, will out preform an Atom CPU with the same internal clock.

Using third party software to manage visual themes increases the use of memory for your operating system and in some cases video memory , depending on your hardware will be the impact on performance.

This is no issue. First of all, SSDs have greatly improved during the last years. Overprovisioning and wear levelling (and to a small amount, the TRIM command, though not applicable in your case) have made them quite suitable as heavy-duty, general-purpose disks. I am not using anything but SSD on my development PC (which regularly does a lot of compiling) ...

Following the short & sweet approach my oversimplified answer (strictly restricted to your main confusion) is: As long as your OS has enough (for worst case scenarios) space to fulfill its duties like paging/swapping/etc. Other software also have sufficient space for their respective needs. Hard disk is defragmented. Then you can't tell difference ...

Let's assume your import involves no updates and no deletions. So you are doing all insertions. This should only be writing new data to the transaction log. This means as data is added, it is always being written to a new sector. There might be some buffers/swap that gets churned/written to multiple times, but ignoring that, all of those inserts would ...

As the poster of this writeup on SSDs said, what is really harmful is again and again writing small chunks of data. bits are stored into {1,2,3}-bit cells. These have limited lifespan. cells are grouped into [2-16]KB pages (smallest writeable unit) pages are grouped into (128-256 page-)blocks (smallest eraseable unit) for a page to be rewritten, it---and ...

If you are truly interested in figuring out the details then you will need the following question answered: On average how many bytes are in each row? If you can tell me that there are 10 columns, each column is varchar(100), and the encoding is UTF-8 then I can guess at worst case scenario that you have 4,000 bytes worth of data per row and add some more ...

Thank you all for your insights. But it looks like hardware malfunction after all. Thank you @LogicDaemon for suggesting HDD settings check. I have no idea why I stopped monitoring my HDD (Had HDSentinel for that), but in hindsight it was an error, which unveiled when installed said application. HDSentinel reports 527 reallocated sectors and 497 weak ...

Reads are fine, and SSD's can have their bits read from without any detrimental effect. Writes are another matter. Clearing a bit affects the integrity of the bit and after a lot of sequential writes, the bit will stop accepting new writes altogether. It can however still be read. Let me just say that the write limits on new enterprise drives are huge. ...

It really is not a straightforward answer to this. SSDs do not care about continuous writes as much as how many times any particular sector is overwritten. When SSDs first came out, something like SQL was a bad word as the operating system in general treated the drive like a traditional HDD and failures were very frequent. Since then, drives have become ...

Writing to SSDs isn't necessarily bad. It's the writing and rewriting of a single block that's bad. Meaning if you write a file delete it then write it again, or make small amounts of changes to a file over and over again. This causes wear on the SSD's. Databases would definitely fit into this category. However according to this article, petabytes of ...

SSD's do not like it. If you keep max write speed up for 5-10 years (24 hours per day, 7 days per week) then you might end up with a broken SSD. Ofc. After 5 years most servers have reached their economical end of life. Disclaimer: Do not try this with the very first generation of SSD. Those where less robust.

My guesses: HDD transfer mode degraded from DMA to PIO. Usually this is due to bad contact or semi-broken cables. When in PIO mode, any HDD access takes a lot of CPU power. But if HDD is connected with hard-soldered-to-board slot, hardly this is the reason. Overheating and throttling due to dead cooler. If CPU is overheat, it will drop frequency to lower ...

Chances are your laptop is simply becoming very old. Most of your computers components simply can't keep up with the demands of Windows 7 and passive antivirus programs.

Svchost.exe is a container for services. It's worth checking if it's the same service that is regularly spiking CPU use. Look inside svchost.exe instances either with SysInternals Process Explorer or from the command line with tasklist /svc

Well first of all as you mentioned yourself the laptop isn't just old, it's incredibly old and quite frankly amazing that it is still alive. But you also have done a lot of maintenance on it. The CPU it has wasn't great to begin with and wasn't really made for heavy task sets, in fact it was from factory standard slower than most tablets made today. Adding ...

Install the 32/64-bit OS versions required by your applications. Your 2900 will run either just fine. Specifically use 64-bit OSes where you need more than 4GB of virtual machine memory.

All of the other answers are technically correct - however I've always found that this simple example explains it best.

I'm just adding an answer to compliment Mario's answer and all the various comments. In all Intel's documentation an OS requirement is never mentioned in relation to enabling multi-channel memory. Here's an example. In the above example, the benchmarks Intel ran were on a Windows XP 32-bit configuration. Additionally, there are certain editions of 32-bit ...

Somewhere inside a traditional hard disk is a spinning metal platter that actually holds the bits and bytes. As data is added to the platter, the disk controller stores it on the outside of the disk first. As new data is added space is used moving towards the inside of the disk last. With this in mind, there are two effects that cause disk performance to ...

So it seems, that Microsoft published an update in 2013, introducing some new features into the Windows Update engine, including compression of old files. The TIWorker.exe will start to compress files, but the SFC (System File Checker) detects the modified files and restores them back to how there were, causing the TIWorker.exe to crash (you'll see the ...

There are 3 things you could do: Decrease the number of programs running in the background: Disabling Startup Apps Increase the RAM from 2Gb to 4Gb, this would show some difference depending on how you use the machine.

CCleaner is mostly for removing unnecessary files to free disk space and for fixing registry problems. While freeing disk space may speed up your computer, you shouldn't expect huge improvement. It seems to me that your system is low on memory. To run Windows 7 with acceptable performance you should have at least 3 GB RAM. Additional 1 GB should make a ...

Flash disks can definitely get slower when they are full or fragmented, though the mechanisms for slowdown are unlike any that would occur with a physical hard drive. A typical flash memory chip will be divided into some number of erase blocks, each of which consists of a large number (hundreds, if not thousands) of write pages, and will support three ...

One effect on spinning drives that I haven't seen mentioned: Access speed and data transfer speed is different on different parts of a disk. A disk rotates at fixed speed. The tracks at the outside of a disk are longer and therefore can hold more data per track than the tracks at the inside. If your drive can read 100 MB/sec from the outermost tracks, the ...

A computer that's had very little disk space, on a spinning mechanical hard drive, for a significant amount of time, will generally become slower as file fragmentation grows. Increased fragmentation means slow reads – very slow in extreme cases. Once a computer is in this state, freeing disk space will not actually fix the problem. You'd also need to ...

Here, I wrote a book by accident. Get some coffee first. Why does emptying disk space speed up computers? It doesn't, at least not on its own. This is a really common myth. The reason it is a common myth is because filling up your hard drive often happens at the same time as other things that traditionally could slow down† your computer. SSD ...

In addition to Nathanial Meek's explanation for HDDs, there is a different scenario for SSDs. SSDs are not sensitive to scattered data because the access time to any place on the SSD is the same. The typical SSD access time is 0.1ms versus a typical HDD access time of 10 to 15ms. It is, however, sensitive to data that is already written on the SSD Unlike ...

You pretty much nailed it. You can think of a SATA HDD as a half duplex communications medium (That is, it can only accept or transmit data at a time. Not both.) so when the drive is held up for an extended time looking for a free location to write to, it can't read any data to you. As a rule of thumb, you shouldn't load your drives up over 80% capacity for ...

Assuming you are using Windows 7: Open Task Manager and verify that CPU and RAM are not terribly maxed out for some reason. Click on the Performance Tab and click Resource Monitor.

I have a very similar situation with my Compaq CQ20-130TU with Intel Core 2 Duo P8400 (2.26GHz, dual core, 45nm, 3MB cache) After ruling out factors of BIOS, OS, RAM, HDD and overheating, my conclusion is the AC power supply. When my laptop runs on battery power, the CPU performs speedstep normally. However once I plugged in the (potentially faulty) AC ...

While the System is quite likely to use whatever RAM you throw at it (after enough I/O), it does by far not need all of that. All usual Distributions of Linux are preconfigured to aggressivly use RAM as a disk cache if - and only if - it is not needed elsewhere: The head of the output of top will look something like Tasks: 407 total, 3 running, 404 ...

Yes, your assumptions are correct. Windows XP 32bit will only be able to access 4GB (which is half your total), but the mainboard won't care about this limitation (assuming it supports up to 8GB or more). The abstraction on how the memory is addressed or used happens (as far as I know) on the hardware level. As such it won't matter that Windows XP 32bit ...

I had this problem too with cable. Basically its probably everyone being home after work and streaming, and you're sharing the same copper wire going down your street with everyone else and the bandwidth for the neighborhood is just not sufficient.

The specs for the switch say it is only capable of 23 MBps forwarding rate, which means when it is doing layer 3 routing, rather than just ethernet layer 2 switching. It must be configured to do routing and that is why it is slow. Reconfigure it to not use layer 3 routing and just forward the layer 2 switching.

This is done by the kernel scheduler, when a process is scheduled to run, the time it is running is added to the total for that process. The scheduler chooses a process to run 100 to 1000 times per second, depending on the OS and the configuration. (This amount of time is the time slice.) A sleep(10) will use less than a microsecond of CPU time because it ...

Yes the 4GB could very well be the problem. It's clearly being topped out in your picture. All the Windows 8 computers I've worked on (literally thousands) have had 1 open DIMM slot. So the upgrade is up to you. 2GB/4GB/Etc... The speeds don't usually have to match up in today's day and age so that also if for you to decide. Obviously the more the merrier. ...

The screen-size on the Yoga 2 laptop is much larger. Dxdiag shows : Display Mode: 3200 x 1800 (32 bit) (60Hz).

Your bottlenecks could be on internal bus - link between north and south bridge. North bridge connects CPU and RAM, while south bridge works with peripherals like SATA storage. Although nowadays you will probably limited by SATA interface itself, which will be around 500MB/s. Alternative interfaces like PCI could run up to 2GB/s. I doubt you will want to ...

The performance lag of the SSD and CPU will be minimal, as the CPU will in all likelihood have Intel SpeedStep (or TurboBoost*), which will enable the CPU to effectively overclock itself to a higher rating (For example, my NetBooks Core i5 runs natively at 1.5GHz but will boost to 2.3GHz if need be.) As long as the CPU is at least a dual core (hopefully ...
