I just ran across the following link while dealing with some firewall issues
and it mentions a couple of performance tweaks that others might be
interested in, so here's the link:
http://www.sans.org/infosecFAQ/win/failed.htm
In particular, here are the ones that I looked at (requires using regedit):
---------------snip---------------------------------------------------
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem
Data Type: Reg_Dword
Value Name: NtfsDisableLastAccessUpdate
Value: 1
If you have a large number of directories this setting will allow you better
performance when using explorer or DIR command, etc.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Memory
Management
Data Type: Reg_Dword
Value Name: SecondLevelDataCache
Value: 0
If you have a direct-mapped L2 cache, which is not properly detected, set
the value in decimal. For example, if you have 512K cache, set the entry to
512 in decimal (Hexadecimal 200).
If you have lots of memory (over 256Mb or more), set DisablePagingExecutive,
then type REG_DWORD, to 1. This will allow drivers and the kernel code to be
kept in memory. The default is 0 which pages drivers and kernel code when
needed. Since you are still in this area you may consider the following as
well:
IoPageLockLimit and set Reg_Dword to 65536 (Decimal) FOR computers with
256MB of memory or more. It will create a problem if you set it for this
level if your memory is not 256MB or more. For 128+ MB, set it to 16384
--------------------------------endsnip--------------------------
The last two are the only ones I used so far and I think I see an immediate
settling down of the amount of disk activity when starting programs and this
might translate into some benefits overall using CAD for folks with large
RAM systems.
