have you disable Superfetch on your ssd installation?

Hi

have you disabled Superfetch ?
disabling the service Superfetch and regedit

Code:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters

EnablePrefetcher=0

thanks

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 articleabout enabling it for boot files only.

Code:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters

EnablePrefetcher=0

You could use this as well, but as stated before, on SSD Windows should set it automatically.

Code:

reg add "HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters" /v "EnableSuperfetch" /t REG_DWORD /d 0 /f

mine is Dword:0x0000003

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

it's odd that the folder

Code:

c:WindowsPrefetchReadyBoot

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.
