Hi Sam,

Ref: Broadcom Ethernet NIC NetXtreme II locking drbd and terrible 

These keys are on the DELL version.  If like me you have the HP version, 
no such luck :)  I believe they are on the RHS and look a little like an 
RJ45 plug...

I believe the TOE is used by the onboard iSUSE system, which might be 
the cause of the problem.  Maybe it's always running and can't cope with 
DRBD loading so reduces the NIC ability???  Something like that...

Problem Update

I have made some more progress on the subject.  Although upgrading the 
firmware has helped a lot, it's not the entire story.  I found that my 
kernels ( had an old version of the bnx2 driver, version 1.4.14.

I upgraded to 1.6.7b from here:


With the latest firmware *and* the latest driver, this has made a 
significant difference.  The load on the server is reduced to almost 
nothing and my throughput from MySql has increased dramatically.
