Chalk up another 82558B that it works on. I started using it shortly after you mentioned this patch a couple of days ago and haven't experienced any problems. While doing a large file transfer between two FreeBSD boxes, performance definately did not suffer. I got 11MB/sec over FTP. When communicating with a Windows NT server over SMB, though, performance was bad (max 1.2MB/sec). I haven't yet checked to see if this is because of the interrupt coalescing or if it is just because Windows sucks. I did notice a 33% decrease in interrupts (if about 900 packets came in, about 600 interrupts were generated), so it definately worked. If I get real brave I might try it on my router which has mostly 82558B's but also an 82559 or two. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet - Available for IA32 (Intel x86) and Alpha architectures - IA64, PowerPC, UltraSPARC, and ARM architectures under development - http://www.freebsd.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
