IRQ tweak

[NorthMan]

hello.

On some homepages (example tweakxp.com) you can tweak your system to priorities your IRQs. Like "IRQ16=4096" and "IRQ16Priority", does these tweaks work or is it just bull****?

With Windows 98, ME "IRQ#=4096" is valid and can speed up your connection.

For 2000, NT or XP the priority tweak works.

Actually, IRQ priorities (in the registry) are about as false as the QoS tweak. They don't work because that isn't how Windwows operates.

IRQ priority happens in Windows based on the IRQ number; the higher the number, the higher the priority. However, XP uses virtual IRQs. There's no proof from TechNet that IRQ priority settings in the registry actually work (or are even read by XP)

By the way, with the QoS thing? Windows can allocate up to 20% of your bandwidth to a QoS device. However, for this to actually happen, you have to actually be using a QoS device, and that device has to actually use the 20%. If you are at home, you aren't (your ISPs router doesn't support it) so XP doesn't allocate anything.
