Hi.
I have been tweaking my XP for a long time, and arrived at some ultimate stuff. First of all, on multicpu computers, multicpu versions of Hal and Kernel are necessary. I have also modified Win32priorityseparation. Then disabling drivers that are not necessary, processes, services, etc, everything that reduces background activity. ("Processhacker" can help with that).
I have also removed extra networking layers. This gives
The general impression of the computer is a total upgrade, much smoother framerates in games, completely stable latencies of 1 ms with ASIO drivers etc. Since OS jitter is the problem reduced here, this generally means that as long as OS-jitter bothers a machine, general impression of speed and smoothness requires OS-jitter reduction.
Additional hardware consideration, might be trying to spread threads out on cores. How successful the OS is with this in practise I do not know. Or using Intel E5 cpus, with intergrated PCI-e for even smoother gfx, or possibly other things. Much more expensive though, so one probably should consider having a good reason for that.
.I think I pretty much covered anything, but if anyone with more knowledge of Windows XP knows improvements to it, please post.
Best Regards,
Greenleaf River.
