low throuput with 1Gbit on 2810 between 2 switches

Hello all,

i have a problem regarding my current setup.

I configured two 2810 Switches with following Firmware:
Image stamp: /sw/code/build/bass(bass)
Jun 6 2006 14:11:54
N.10.02
419
Boot Image: Primary

following features are enabled/disabled
1)all ports: no flow controll
2)all ports: broadcast-limit 30
3)qos-passthrough-mode enabled
4)Speed Duplex RJ45 Ports: manually configured to auto-1000

Problem:
If i try to copy a 7GB Folder from one Server to an other Server, witch are located on the two Switches, the Throughput is very poor.
If i try to copy the same 7GB Folder between 2 Servers on the same Switch the Throughput is OK

any suggestions?

Hi !

I advise you to upgrade the firmware to N.11.08 and do the same tests again.
