Zero-Copy TCP and UDP Output in NetBSD

-is writes "Jason R. Thorpe has recently added experimental code to NetBSD-current, that enables zero-copy for TCP and UDP on the transmit-side. These changes could mean significant performance improvements for FTP, WWW, and Samba servers. See Jason's announcement to the current-users mailing list for details." From the text: " On tests on an embedded system with limited memory bandwith, TCP transmit performance on 100baseTX-FDX went from ~6500KB/s to ~11100KB/s, a significant improvement." Excellent!
