Problem with HTTP traffic (very slow)

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
