Hi;
In our environment we use Cisco 3560x series switches for servers.
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 54 WS-C3560X-48 12.2(53)SE2 C3560E-UNIVERSALK9-M
All ports have speed 1000 and duplex full configuration. On the same switch when we copy file test between windows servers , speed is normal (single file 5 gb approximately 80 seconds ). But when we test with linux or solaris servers, we maximum see 14 - 30 mb/s (single file) .For gigabit performance i think its bad.
What do you suggest to fix this issue ?
Tnanks,
Best regards

I would go first for a sniffer trace (via SPAN/monitor session). This will tell you if 'slowness' is due to inter-packet delay or packet loss. If it's due to packet loss (i.e. if there are restransmission), look for interface stats/errors at interface level.
If it's interpacket delay, troubleshooting is much more complex and could have various causes (like buffer allocation problem,etc...). Best is to investigate this via a TAC Service Request in that later case.
Thx,
Fabrice
