The data transfer rate between the linux servers here is very slow.



Hi,

The data transfer rate between the linux servers here is very slow.  For
example scp to copy a folder from one machine to another machine takes a
long time.  The scp shows a speed only between 700KB to 1MB per second.  How
can I improve the speed, please guide me.  I tried the following:

[root bangapps 9.1]# ethtool eth0
Settings for eth0:
        Supported ports: [ TP ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Supports auto-negotiation: Yes
