I have two machines running 4.8-RELEASE ... both sitting on the same switch, same hardware, same everything really. One gets 200k/s using wget / curl / w3m to a http address the other gets 6k/s to the same address. On the slow http machine I get 200k/s via scp or ftp to the same address it's just web traffic that is slow (note web traffic to all other locations is 4 - 6k/s as well). I've recompiled curl, w3m, wget and all their dependancies and still no luck so I can only assume something is broken with http traffic on this machine. The only difference between these two machines is one is an nfs server and the other an nfs client to that machine. Has anyone experienced this before / got any pointers on where I should look, which deity I should pray to etc. Cheers, -- Mark Sergeant <msergeant@snsonline.net> SNSOnline Technical Services

Into NFS, or a local file system? Does it differ for the two machines? Robert N M Watson FreeBSD Core Team, TrustedBSD Projects robert@fledge.watson.org Network Associates Laboratories
Hello,
Have noticed if there's any inconsistent full-duplex/half-duplex setting on
nics
and switch ports? See if the settings are the same on the 2 boxes.
Recently we've been tottaly confused about vey new Dell boxes pluggled into
Dell siwtches experiencing *very* poor performance running
FBSD-4.{7,8}-STABLE
and after lots of struggle we've solved the problem setting their nics to
'auto'
instead of the original fixed setting 100baseTX Full-duplex. Go figure...
Best regards,
Alex
