Download speeds very low =ftp tests

[dbellamkonda]

Hey ,, i ran into a issue here,

few servers are connected directly to 6509 to gig ports with a speeds of 1000 full on either side and they are having a slow download speeds of 11 Mbps

if i try to download an ftp from any of these servers ,,,download speeds are at 11Mbps.

in the same switch speed is good between two servers and rest of the servers operate at low sppeds.

If i try to involve another server connected to another switch,,, it is 28Mbps.

can any one help me out figure out the issue.

I am not able to figure out the issue

Thnx

Hi,

check L1/2 errors on uplink ports.

There were no errors on any of the ports

ok. if L1 is clear, try tcpdump on server and client side. maybe there are some errors in tcp communication, or something like this.
