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."

That's definitely not normal. Even my Disk I/O is better than that on a 5 year old P4 Linux system (around 50MB/s to a plain old PATA drive). PCI should be capable of 133MB/s and GigE is 128MB/s.

The point is, regardless of throughput speed, the processor time consumption of Linux network code seems to be far lower than that of Vista.
