Actually no; at least not in 4.2-R. See the following PR: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=11525 Those issues weren't exactly related to performance (bandwidth), but they can cause a lot of network functions (rpc, mrouted, etc.) to either not working correctly, or not working at all when you have dynamically attached Ethernet interfaces (PCMCIA NICs) plus a lot ( > 32) of virtual interfaces (gif, tun). > Sorry if this isn't so helpful, but I can't remeber > anyone recently popping up and complaining about the perf with > lotsa NICs in machine. We emailed a follow-up to the list a few months back regarding the PR, but didn't hear anything. Guess people don't use that many gifs in their notebooks. :-) yushun. ____________________________________________________________________________ Yu-Shun Wang Information Sciences Institute University of Southern California To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
