2848 very slow copy bandwith/throughput ...

[foler]

hello...
We have 2848 switch connected to PC machines and some windows servers. Many of them is dell precission 690 workstations. But, copy between hosts is very slow, arround 6Mb/s. I am try to copy between different machines with different nic configuration but all of them have slow perfomance.
QoS is enabled on all ports, ip routing is disabled, speed is auto, flow control is enabled, qos-passthrough-mode is enabled with mode optimized, stp enabled with rstp protocol, ...

How I can configure this switch for better bandwith?

thanks
