Windows 7: Master File Table Size?

Master File Table Size?

I remember seeing a tweak about changing the MFT from the default DWORD 1 (12.5%) up to 4 (50%), but this was a long time ago. I'd assume changing it's size has some effect on system speed if you were closing in on max space, but lets say on an SSD would it even be wise to consider changing it's size. I leave mine alone as is, but I can't seem to find any info on the subject other than general info.

Leave it alone. That doesn't need to be changed by the user. It's not gonna speed up your system, you should keep that in mind mate.

Figured as much. Thanks for the response. I ask in regards to a friend who sent me a few tweaks, but I don't wish to use them, I do like researching them however. any take on the following? He has said playing with the memory management has helped his system, which I'm in doubt of:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
DisablePagingExecutive"

"LargeSystemCache"

"NonPagedPoolQuota

"NonPagedPoolSize"

"PagedPoolQuota"

"PagedPoolSize"

"SessionViewSize"

"SessionPoolSize"

"WriteWatch"

Nice academic exercise - but useless and dangerous.

LOL I told him if he keeps tweaking he'll end up with a giant paper weight on his desk, I guess some people only learn after it's too late. I'll just have him join the forums to post any others he has in mind and you gurus can give him the real reason as to why these could cause more harm than good

It is OK to tinker with your system as long as you make an image before you start. Then you can always easily get back to a running system when things go on the blink.

But if you tinker with the file system, you better have no essential data on the disk with which you experiment.

I've always thought 7 was pretty good out of the box. I enjoy some visual/ context menu tweaks, but I figure he has a quad core and SSD with 8 GB ram, performance tweaks really are not going to help improve much

1. Disablepagingexecutive: Changing this value to 1 "forces" Windows to keep the kernel in RAM and not page it to the pagefile. Pretty useless. Windows 7 is quite smart on this part. It keeps the kernel in RAM whenever possible automatically, no need to tweak -- and it's always there in the memory if you have plenty of it (4 gigs and above).

2. Largesystemcache: Changing this value is known to bog/slow the system down. This tweak only helps in server environments, not for general users like us.

For the rest of those, I've no idea of what they do. But I'm quite certain that changing them is going to hurt, so stay away from them for good.

Do like whs suggested. Make a image first before doing this tinkering. You will need it. You will discover that Windows 7 isn't like XP very few tinkers help.

You are absolutely right. I have such a configuration (i7, SSD, 8GB RAM) and if that system would run any faster, I would get whiplash, LOL.
