[jQuery] Improving jQuery Timers Applications
I am interested to hear any test reports for jQuery applications that
are using AJAX, any animation for PCs that might have altered the
system timer resolution.
I posted an entry at my blog with discussing this, with a C/C++
utility you can use to test to see how your applications behave in
normal sleep mode vs "fast Sleep" mode.

Here is the fastsleep.cpp comments:
// Utility to toggle the PC with Windows OS multi-media
// resolution that speeds up the Sleep() quantum.
//
// All PC has a quantum of 10-15ms regardless of the
// sleep value. Assuming the PC is 15ms, if you use
// Sleep(1), the time slice is 15ms. Sleep(18) is 30ms,
// and so on.
//
// This utility allows you to toggle the resolution
// to 1 ms. The actual delay is shown by this utility.
//
// Why?
//
// This can change the behavior of your applications
// which depends on timers, like many of the Web 2.0
// Javascript applications. In Windows, the multi media
// function timeBeginPeriod() changes the resolution
// for the entire system. So if some other application
// is running with timeBeginPeriod(1) enabled, this
// will have a drastic effect on your Web 2.0 application.
// It may behave better, it may behave unexpectedly worst.
// It might explain someone reported to you, "hey this
// is not running right." But others don't see this,
// and you can't repeat it, so you just blew the report
// away. This utility can be use to design your
// application properly under all conditions.
