The concept of cores is not that simple. Logical cores are the number of Physical cores times the number of threads that can run on each cores. This is known as HyperThreading. If I have a computer that has a 4-core processor, runs two threads per core, then I have a 8 logical processors. You can see your computers core capabilities by running lscpu command. ...

Even with many more cores than tasks, they won’t scale perfectly. That’s because some state is almost always shared. Not necessarily in the task, but the kernel, for example. Or they may access the same resource, like the network or a disk or whatever. SMT (ie. Hyper-Threading) may rely on the fact that different tasks use different CPU execution units. As ...

Bit old now, but i have long pondered this. My 8gb laptop w/ ssd seems to struggle and swap out a bit. Not sure can be fagged upgrading the laptop, but it has a sata dvd port i could use for a spare ssd i have, and use the second ssd as a slave to do swapping & temp files. There is of course also the issue of bandwidth available to the southbridge ...

The clock speed requirement is meaningless. The software doesn't care how the CPU gets its performance, just how well it performs. Minimum clock speed requirements have been obsolete and close to meaningless for about 10 years now. A typical i5 2.4GHz dual core laptop CPU will have a passmark CPU rating of about 4,000. A typical 2.1GHz Core2 dual core ...

Ask yourself the obvious question: If the processors ran consistently at 2.4Ghz, wouldnt they market them at 2.4Ghz? From Wikipedia: The increased clock rate is limited by the processor's power, current and thermal limits, as well as the number of cores currently in use and the maximum frequency of the active cores. When the workload on the processor ...

If the speed of the RAM is slower in the replacement set, then that could also contribute to the issue. RAM is not all about capacity. edit - although you mention CPU is at 100%, is this during the usual daily tasks? Can you see which process is using the CPU time? It is certainly possible you have found a new bottleneck if the load has increased.

First of all you should know that increased RAM results in greater power usage so it's not always effective to just add up more and more RAM to make the system faster, other things like processor,clock speed etc. affect the speed of the system as well. So YES adding up unnecessary amount of RAM may slow down your system and will surely decrease battery life ...

Yes, it is related with the Power Settings in your system. When you check the Power Options in your system, we can set different state value for processor: On battery and Plugged in. By default, the value of the Maximum processor state when using battery is lower than plugged in state. Please change the value as you wished to make the laptop running ...

Usually the slow speeds are indicators of a failing drive, so it was a good decision to run chkdsk on it to see what the results will be. However, in order to be sure I'd suggest to run another test but this time instead of the OS tool I will recommend to check in the official manufacturer website if a diagnostic tool is available to use and run a test with ...

Unusual sounds and intermittent slow response usually indicates a failing drive. Get your data copied to another drive and pull the misbehaving hard drive out of service.

In worst case scenarios, sure, it should. That said, swap is usually the last place you'd store pages on, if ram was available, and with 6gb, you should typically not be experiencing that much swapping. Typically system slowdowns due to swap would be due to insufficient ram + high ram demand (which results in heavy swapping) + slow drives - I've had ...

I've seen this occur before and spent time trying to figure it out and later determined it was something so simple, I wanted to add an answer for you just in case this is what's causing you this very similar sounding problem.

I would guess that Notepad++ might take a while if you have syntax coloring enabled, and if it is a C or Java file, looking for sub-routines, functions, etc. Not familiar with Pluma. If it is a programming code file, you could copy it to have a .txt extension, and open that version, and see if it opens faster.

Although this isn't a solution to the root cause of the issue (the poor performance) it might help a little in dealing with it: you might want to go to System → Advanced system settings → Performance frame, Settings button, then select "Adjust for best performance". This should stop Windows from trying to animate when you minimize a window, for ...

I found the answer. It was the cable. They were connected by cable type Cat 5E. I'd been thinking what is wrong with this and finally I just tried to change another cable then it solved. One thing I still couldn't figure out is why upload was faster at that time. If the cable has a problem then It should effected Upload speed too but it wasn't

The fact that the 4K random speeds did not increase as much as expected when the queue depth is increased to 32 probably means that NCQ is not in effect. Usually that's because SATA mode is not AHCI but IDE compatibility. In Linux that can be caused by the boot parameter libata.force=noncq. P.S. In my past experience, when my SSD suffered performance ...

@Rakitić it seems your system is aging, thus, your issue my involves dust, drivers compatibility problems, and might also have some faulty chips. Basically, freezes mostly occurs from of the Followings : RAMs (It might be faulty or needs to be increased or replaced.)

There are a couple of things I would check - The SMART status of the hard drive. This could tell you if the drive is starting to have issues. If the heatsink is clogged or the fans have stopped working on the drive.

Your AMD 8350 is 4GHz, with 4.2Ghz "Turbo Boost"/"Turbo Core". The machine will run at 4Ghz or less, unless you are hammering away on something specifically CPU intensive (like processing video files). At this point the CPU will shutdown parts if itself it feels you're not using for the task, and uses those resources to bump your clock speed above 4Ghz ...

Short answer: This is completely normal. Don't worry. Long answer: CPU working clock is a complex thing. The company announces a clock speed for it but the CPU rarely ever works as exactly. There are several things that you should consider: The manufacturer has announced a round decimal number as the working clock speed but electrons and atoms of the ...

It would appear that you're not the only one to have this issue as you can see here, (I know that page is for routers). It's possible that the firmware you're using is causing issues, which could explain why the other modems that were sent to you also have the same problems, they're all on the latest/same firmware. You'll probably have to contact your ISP ...

It's very rare that device drivers would cause sluggishness. Certainly the built in, well tested ones are extremely unlikely to (unless you have a hardware issue which is causing it), so if anything you would need to look for third party device drivers and uninstall those, like you did in your case. On the other hand bugs with graphical (i.e. Nvidia and AMD) ...

You have to identify which service is causing it. First go into Services. Type it in the start Menu, or enable administrative tools in the start menu if it's not there already. Under services group them by which is running and see if there's any third-party, not windows service. You can stop and disable that. If you don't find anything unusual there, ...

There could be multiple reasons for this. It could be a configuration issue on your computer, it could be a router problem or it could be a network problem with your ISP. You should start by trying the same network with a different computer. If the other computer also has the same speed next step is to try resetting your router or checking router ...

Sorry meant to put this as an answer... if your computer hangs for 10-20 seconds before loading BIOS that's definitely a hardware issue it has nothing to do with your OS. You should try taking out the RAM and reinserting again, perhaps try a different slot or see if there might be dust on it. Also check if you might have disturbed other components while you ...

There will be little to no measurable difference for pure computational tasks, or the differences will be masked by other things such as disk access or other OS features taking precedence.

If you got a used SSD, you need to run a TRIM. In windows 10, this is done automatically, but in windows 7, you need to get the SSD manufacturer's tools for this (which for your SSD is probably Samsung Magician and then select something like "optimize").

This is actually quite an interesting question. To answer it, I need to give you a brief over view on how games are typically written these days. But yes, the article is sort of right.

That's simple. Any system always has a single bottleneck, its weakest element that limits overall performance. Any improvement outside of the bottleneck is useless (and sometimes harmful). If switching to SSD doesn't improve the performance of your application (game etc.), then disk i/o is not it's bottleneck. To find the right place to improve, monitor ...

The average consumer can not buy a 100 core CPU, they don't exist in that market space. CPU can do more complex work. GPUs have hundreds or thousands of cores, mine has 4096, so they will complete the job way faster than a CPU. Only certain types of works loads are well suited to the GPU though. 4000*800Mhz=3200Ghz. There is overhead, and some ...

There's no known threshold for that. If WBC enabled all writes will go to flash regardless of their size. The only case they go to disk bypassing flash is when flash is already full and flushing it before acknowledging newer write is pointless: latency will spike all over the roof.

As @txtechhelp Provided the answer to my question is GPGPU. General-purpose computing on graphics processing units (GPGPU, rarely GPGP or GP²U) is the use of a graphics processing unit (GPU), which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit (CPU).[1][2]...

First off its a hard disk not disc. Disc with a "C" is for optical media, like CD-ROMs and DVDs. Now, on to your question as to why a SSDs dont necessarily improve the speed of running applications compared to a traditional HDD. The reason is disk access. SSDs do read and write much faster than traditional hard disks. However, unless the application is ...

A. when your system starts to swap, you are already in trouble. You don't won't to get there, ever. B. SSD are faster than conventional hard disks, but they are still significantly slower than RAM memory. A running game in an adequately designed system uses only CPU, GPU, and RAM, and the hard disk is only accessed for saving game status or such. Therefore,...

Generally swapping only occurs when you start running out of RAM. With today's systems with 16GB and higher, it is unlikely that playing games would cause swapping to occur. If swapping does occur, then yes, it would be much faster when using an SSD than a HDD. However, the page file is often disabled on SSDs to limit the number of writes and thus increase ...

While it's not listed in the man page of openssl speed, it can still measure aes speed (on my machine at least). Running openssl speed {some random value} will print an error message that includes the list of ciphers it can test.
