Windows Robert Love, a famous Linux kernel hacker, has written a blog entry with his thoughs on the recently posted Vista's network slowdown issue and the explanation given by Mark Russinovich: "Unlike DPCs, however, the Linux parallel does not consume nearly half of your CPU. There is no excusable reason why processing IP packets should so damagingly affect the system. Thus, this absolutely abysmal networking performance should be an issue in and of itself, but the Windows developers decided to focus on a secondary effect."

RE[2]: Awful situation

"Wow that 300mhz P2 must have a hell of a system bus. "

Depends almost entirely on the number of packets per second and not on the bits per second. More packets, more interrupts, more CPU load. This is why gigabit nic's have interrupt mitigation and large buffers. If you use large packets you can get very respectable bps on low end hardware.
Still, 1gbps on a 300mhz p2 is suspiciously high.

"I have a 3.8ghz P4 at work that couldn't get above 40 megabytes per second in throughput."

This, on the other hand, is suspiciously low.
