Some Notes on the Machines

The following:

provides a thorough DirectX updater for Windows 7. It downloads and updates quite a wide variety of items. If you have a game or application missing a DirectX file, try this.

This:

is really intended for use to test realtime kernel audio configurations. However, the Perl script above does form a very good overall Linux performance optimization test, you can ignore a few items you may not need.

If you see this, find OUTLOOK.EXE, go to Properties, and check the Compatibility tab. It may be set to XP SP2 compatibility. Uncheck Compatibility mode if it’s set.

No clues yet as to what is causing this, but I’ve seen it as the only solution needed once, and I have multiple reports similarly.

Sometimes IPv6 is installed on XP in a hidden form — sometimes IPv6 may be installed, but not visible in any Windows GUI. To find out, go to command prompt and enter:

netsh show helper

If IPv6 is installed, in that list will be “ipv6”. To uninstall on XP, run this:

ipv6 uninstall

The ipv6 command does not exist on Server 2003. The following does:

netsh delete ipv6mon.dll

Hidden IPv6 has been shown to cause problems in some Oracle environments.

At this registry location:

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Executive

create or modify “AdditionalCriticalWorkerThreads” and also “AdditionalDelayedWorkerThreads”, both DWORDs.

For a 32-bit system, I have come to prefer decimal values of 6 times the number of gigs of RAM. So a 1/2G RAM system gets 3, a 4G system gets 24.

I’m still working on a formula for 64-bit OS, I’d like to know whether Windows can reliably hold the same up to large RAM (64G=384 ??!?). Until I have better, I’ll be using the same as 32-bit up to 4G RAM, and upwards of 4, I’ll use 3 times the number of gigs of RAM. So 4G of RAM gives us 24 (4×6), but 8G also gives us 24, and 16 gives us 48.

Some outdated info on this is here:

http://msdn.microsoft.com/en-us/library/ee377058%28v=BTS.10%29.aspx

The above includes a statement that the maximum value actually used by Windows for these entries is 16. However, the page is old enough that it does not discuss 64-bit environments. On the other hand, the MZ 7 Optimizer does set these registry entries to 16 on any 64-bit server when the appropriate checkbox is used.

This utility:

http://shutter-project.org

appears to be excellent. Packages available for several distros.

The entire list appears to be here:

Try this:

First get a list of interfaces:

wmic nicconfig get caption,index,TcpipNetbiosOptions

Make note of the number of the interface you want to change. Once you have it (for example, number 0000009), do this to enable:

wmic nicconfig where index=9 call SetTcpipNetbios 1

List of options:

0 – Use NetBIOS setting from the DHCP server
1 – Enable NetBIOS over TCP/IP
2 – Disable NetBIOS over TCP/IP

This works quite well from XP to 7.  Does not transfer applications.
