[GoogleCodeExporter]

We have done one set of testing between Linux PC to PC using iperf, but errors 
are observed at the Rx side:
"RX packets:1394337434 errors:0 dropped:5 overruns:0 frame:1"

Used Iperf version: 2.0.5 (08 Jul 2010)

The Ubuntu versions are:
Server : Ubuntu 9.04 
Client : Ubuntu 12.04
Date   : 24-Jan-2014 
Tested Time in seconds : 18175

Please let us know why does the error occur while doing iperf between PC to PC.

Attaching log for reference.

This is nothing to do with iperf 

Receiver overruns usually occur when packets come in faster than the kernel can 
service the last interrupt. 

you can try with increase the ring buffer of the NIC 
# ethtool -G eth0 rx 1020

Agreed, this is not an iperf issue.

Closing.
