[Veritas-bu] Sun Gigabit Performance
2001-02-14 10:38:27
I run the ucd-snmpd package on my backup servers and use cricket to graph the
interface throughput. It gives me pretty good stats on in/out traffic for the
interface. I only manage to push about 90mbit on a 100mbit interface, but I'm
sure I could do more tuning to increase it. I'm getting a gig-ethernet
adapter soon to put into a 220, if I get stats I'll post them.
Oh, and have you thought about tuning your interface for better performance?
Nice little article in adjusting TCP buffers, etc. in this months ;Login from
Usenix.
