Windows 10: have you disable Superfetch on your ssd installation?

Hi

have you disabled Superfetch ?
disabling the service Superfetch and regedit
Code: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters[/quote] EnablePrefetcher=0

thanks

:)

 

How To Optimize Windows 10 Settings For SSD Drive Performance?

I just upgraded to Win10 from Win8.1

One of the suggestions for SSD optimization I had read was to disable the SuperFetch Service. On my machine (laptop with only one drive which is an SSD) SuperFetch was enabled by default.

any comments on pros/cons of disabling the superfetch service?

 

Windows 10 takes to long to start

maybe running msconfig would better inform you what your machine is doing when it starts?

instructions to disable superfetch:

Disable Superfetch & Prefetch for SSD in Windows 10/8/7

(dont disable prefetch)

Defrag your hard drive

This is all assuming your hard drive is the limiting factor, you could run resmon to verify this on your side

 

Windows 10 should do it automatically once it identifies an SSD boot drive. It might require some time/number of reboots before it acts.

 

mine is Dword:0x0000003

does it really matter with 16g ram?

after doing some searching I found this article about enabling it for boot files only.

 

EnablePrefetcher=0[/quote] You could use this as well, but as stated before, on SSD Windows should set it automatically.

Code: reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters" /v "EnableSuperfetch" /t REG_DWORD /d 0 /f[/quote]

 

Superfetch was one of several features that were brought in to help speed up the process on slow computers. Same with pagefile. Microsoft should really spend some time re-evaluating them.

 

I set them for boot files only. We'll see how that works.

 

I'm sorry but you are incorrect I think. SuperFetch is only an elaboration of the XP Prefetcher task (What is Windows SuperFetch). It would be unwise to change it.

The pagefile isn't generally interesting any more (since 20 years or so). You need a small one (400 MB) to create crash dumps but that is it. It was never meant for performance - it was to allow paging of agreed virtual memory somewhere when there was no space in RAM and only if the need arose. If you have enough RAM your pagefile will not be used.

Even up to 10 years ago I used to force certain (small) tables (currency exchange rates and so on that didn't change much) into memory as I thought I knew better than the OS - not any more. The guys who write memory management algorithms are far clever than me.

Honestly, unless you have a PHD in math I'd let it be. What is used often will be in dynamic memory not on disk anyway.

 

hi
i renable the service Superfetch to automatic (i guess it's the default,isn't it? )
after several reboots it's still on *Sad

it's odd that the folder Code: c:\Windows\Prefetch\ReadyBoot\[/quote] is empty

 

I disabled it manually. No need for a thing like Superfetch if the os is installed on a fast SSD.

 

Superfetch monitors which applications you use the most and preloads these into your system memory (RAM) so they'll be ready when you need them.

RAM (memory) will always be faster than a SSD, but yeah Superfetch probably won't be need with a SSD since you probably wouldn't notice any difference.

Superfetch (Memory Prefetcher)

It'll be interesting to see some benchmark numbers with Superfetch enabled and disabled. *Smile

 

Several members of the old OCC forum including myself played around with benchmarks with and without superfetch enabled. Absolutely no difference.

 

To make sure Windows is "optimized" for an SSD or SSD(boot drive) and HDD(Data/Backup drive) all you have to do is run Code: Winsat formal -V[/quote] in an Admin Command Prompt and let Windows take care of everything.

The Winsat command, it is a built-in tool for assessing system performance. You can read more about the Winsat command at TechNet/WinSAT and clicking the different commands there. On Windows 8 through 10, when you run the command listed above, Windows runs the same sorts of tests that it would use if it were calculating a WEI, but the tests and the subsequent reboots cause changes to be made to prefetch, superfetch, and ReadyBoot. Windows will gauge how well your SSD preforms and handle accordingly. It also might turn of one of the three for the SSD, but keep it on for a HDD that's being used a a second internal drive, or an external hard drive that is always connected and on.

The moral of the story and a very good maxim is: Do not tweak, let Windows take care of Windows.
As for me "Been there-Done that" and learned.

 

Thank you. I thought that would be the case.
