We have a 10baseT network here, and Linux NFS is pulling about 20-50K a second from a Sparc Server 1000 one router hop away... FreeBSD is pulling 300-500K a second, easy. I can do exact benchmarks, if you're interested. -- Jim Leonard, SysAdmin at DePaul University and demofreak work: jleonard@condor.depaul.edu home: trixter@mcs.com For a new experience, try http://www.cdrom.com/pub/demos/hornet/html/demos.html
