Again, you are a GENIUS.
Check this out:- http://www.thesycon....clat/dpclat.exe - very small 200k d/l - standalone test application
Its a Windows [ XP32/XP64/Vista ] Low Latency checker.
The lower the values and less spikes the better.
On my XP32 rig and my XP64 rig, it settles down around 7us to 15us and never spikes above 35us to 40us.
With VLite .95 32 bit - fully stripped and most services disabled - it sits around 35us to 75us and peaks every 30/40 seconds at +1000us - thats makes Vista 8 - 10 worse than XP32 or XP64.
Clearly, there is a lot of "stuff" [ crap / drm / polling ] going on in Vista that is not there in XP32 or XP64.
Maybe this tool will help you identify where all the cpu cycles and memory useage is, and how to "dis-integrate" them.
I hope this tool can help you further "cleanse" Vista and identify areas of even further improvement so we will hopefully soon see Vista operating at the same or better speed, efficiency and latecny as a currenlty tweaked XP32 r XP64 system.
Again, you are the man !!
