The article you linked to answers your question. Memory optimizers are not only not needed, they are harmful. Free memory is no better than memory not installed in the device -- it has no effect on performance. Modern operating systems go to elaborate lengths to keep as little memory free as possible to gain maximum performance. You can clearly see in your ...

Yes, there will be some performance drop. Negligible, IMHO. Sata I is not only speed, it's also lack of certain features introduced with later revisions. But, speaking from experience - it doesn't matter. No matter how fast the HDD is, it will be crawling compared to SSD. And, unless you're working with large files constantly, only then you will still have ...

Brief answer: You are not going to loose noticeable speed when you install the older laptop drive on a SATA I/SATA-1.5Gpbs port. Somewhat more verbose: 95MB/sec sustained linear read/write is about the normal max for a HDD. It is actually pretty good for a laptop drive. Lets compare that with SATA. SATA-1.5 has a signal speed of 1.5Gbit/sec. That is ...

The reason why the disk thrashes on wake is due to hybrid sleep. This means that sleep mode acts like both regular ACPI sleep mode (where the system is put in a low-power state) and hibernate (where the memory is written to disk) to keep a balance between performance and reliability. So in case of power failure, the computer can always resort to using the ...

Is there a performance difference when installing an OS on the last partition? Yes. Enough of a difference to matter? Depends on what you're doing, but generally it won't. Partitions are allocated from the outer edge where sequential speed is higher. Later partitions will be closer to the center with slower sequential speeds. You can observe this with ...

They're not necessarily "fake", but having a lot of near useless programs running in the background hogging resources will always slow a machine down. Many of them have active scanners that constantly monitor your system as well, further slowing it down. Using more than one of them is probably overkill as well. I've seen several machines that were brought to ...

Transfer speed is a matter of latency introduced by SATA controller - older and slower SATA I controller will result in slower transfers. It happens, because disk transfer consists of several requests and responses between SATA controller and disk controller, where each one has some latency, not just linear transfer. These latency times sum up and result in ...

Game settings which impact the CPU usage depends on the game itself mainly and also some what depends on the hardware combination used. Generally speaking, the graphics settings that are usually available in the games these days that impacts the CPU are - Draw/View Distance Shadow Quality Anti-Aliasing [AA] (Depends on what type of AA are techniques are ...

Try freeing up disk space. SSD drives tend to take a big performance hit when they have less than 10% free space.

According to Microsoft, tests in their lab showed that "on a particular server in early testing" of RIO, they were able to handle 2Mpps without loss in Windows Server 2008R2, i.e. without RIO 4Mpps on (pre-release) Windows Server 8 using RIO Screenshot from that video (44:33): So the answer to my question Is it possible to process millions of ...

I had the same problem. I enabled AHCI on the BIOS (disable IDE emulation). If you do this Windows won´t start. To solve this, do on CMD as Administrator bcdedit /set {current} safeboot minimal then restart the computer, change BIOS and when Windows restarts in safe mode, execute bcdedit /deletevalue {current} safeboot The next restart the problem ...

In hyper-threading, the idle time of the core for taskA(the said core could have sent a request to the disk for data, wait for the disk to seek the area of the platters, read the data and send it back to the core) is exploited to perform another taskB. So, when taskB is being serviced by the so called thread 2, and if data fetch request by taskA is ...

tl;dr To give a definite answer, more tests seem necessary. But circumstantial evidence suggests Linux is the OS used practically exclusively in the ultra low latency community, which also routinely processes Mpps workloads. That does not mean it is impossible with Windows, but Windows will probably lag behind quite a bit, even though it may be possible to ...

I have some real world evidence for you. I have a VMWare virtual machine with the vmdk file on a standard 5400 RPM 1TB HDD. My boot times were consistently 50-60s. I bought a 5400 RPM 1TB SSHD (model ST1000LM014) and moved the vmdk file over to it. On the first launch of the VM the boot time was about 70s. By the fourth launch the boot time had dropped to ...

If what causes your problems are known processes, you can restrict them using ulimit For example, script the launcher of your app like this: #!/bin/bash ulimit -v 1048576 /usr/bin/greedyapp Your app will be able to get only 1 GiB of virtual memory before getting out-of-memory errors. I've tried it with browsers and it will effectively protect your RAM ...

What kind of liquid was spilled on your PC? When you take the heat sink off the CPU, if it hasn't been removed in a while, I would HIGHLY recommend that you clean off the old thermal compound with some isopropyl alcohol, and apply fresh thermal compound. I'm not saying that this will fix your issue because there is no telling what other items may have been ...

High disk usage is typically caused by many processes making requests for data stored on the disk. In the "Performance" tab of Task Manager, click on "Resource Monitor" and expand the section labelled "Disk". You will be able to see which processes are using the disk.

I'm running crystal disk, the read error rate, reallocated sector counts, seek error and seek time, spin retry counts, are all above the threshhold, actually I think everything is above the threshold, but half of those thresholds are 0. Lots of other things seem bad, like 256 uncorrectable sector counts. This indicates a completely broken hard ...

This Anandtech review suggests that it does do something but probably helps more on USB 2 and small files rather than USB 3. What this suggests to me is that it is essentially a buffer or disk cache layer that can optimise the order that files are written to the device. That makes sense though. There is no way that the software can make the underlying ...

CPU temperatures listed by many motherboards themselves can be based on a sensor that exist under the CPU, and because that is not the actual core temps, they also have applied algorithms that attempt better to guess what the temperature might be. This could be reading about anything, a mix of the motherboard's own heat, and the CPU heat around there, and ...

This makes very little difference - indeed you probably won't notice it. The difference is not nothing, as typical hard drives are faster when reading the outside of the disk then the inside, but you probably won't notice the difference. If you are using an SSD there is no difference.
