Slow network performance

[Dimuthu Parussalla]

Hi Sten,

I have ruled out the faulty cable. Also no errors reporting on the managed
switch. Doing a test with a reduced parameters to 32k.

What have you done to rule out if it's a faulty cable or noise on the
cable? What kind of cable is it?

net.inet.tcp.sendspace=3217968
net.inet.tcp.recvspace=3217968

Are you sure these two should be set to the millions?
Try reducing them to ~32k or so.
