Lustre discuss - Oct 2009 - Lustre performance on SLES 11 x86-64

Hi,

Just an out of the blue suggestion.   Could you try configuring your
eth0 for an MTU of 9000?  This has helped us in the past on a Lustre
1.6.5 CentOS 5.3 system.   I just have the line "MTU=9000" in the
ifcfg-eth0 configuration file.

Cheers!
