Kernel Optimization: /timeres Redux...

Hello cMP-ers

In poking around the Boot.ini innards, I've had occasion to (re)consider the "/timeres" switch. There's a great resource describing the all switches at -> http://smallvoid.com/article/winnt-boot-ini.html.

In this list, "/timeres" parameter is described thus:
/TIMERES=number - Specifies the resolution of the system timer in a multiprocessor environment. The number is 100s of nanoseconds, the supported values are 9766, 19532, 39063, 78125.

Hmmmmmm... looking at the Kernel Optimization page on cicsmemoryplayer.com, the suggested value is "9800".

So I thought I'd "just try it".

Hmmmmmm # 2 - "9766" seems to improve upon the "9800" value. As a benchmark, I removed the /TIMERES completely and yeccccch - THAT definitely alters SQ !

Can somebody else please just try it, and report back ? In the meantime I'm going to do some flip-flop listening and see if I can determine whether it's me (a trick of "expectation") - or the SQ that's changing.

Thanks for playing...

That's not a Toy... IT'S A TOOL !!
