Hi managers,
We are having a problem with slow response time for our interactive
processing. I believe it it a network problem and want to make changes, but
my boss is hesitant to let me do this. Out NIC is running 10BaseT
half-duplex and is connected to a Cisco switch. I am seeing collisions in
netstat that I believe are related to this. I have included the output from
several commands for you're review. Am I on the right track?
Thanks, and I'll summarize...
