[Sunhelp] Bad performance with SUN Gigabit Ethernet cards

[Tayeb Mesbah]

Hi,

We just purchased two SUN Gigabit Ethernet card and we are having very bad performance when using ftp (throughput = 200mbps with back to back test "server to server" or connected to CISCO Catalyst 5505). 

Any idea how to improve the performance with these card? Did I need to do some
kernel tunning "TCP parameters")? 

Please reply to my e-mail address: mesbtay at statcan.ca

Thanks
