[ofa-general] performance and Kernel support

[H. N. HARAKE]

Hi


The second question is regarding performance parameters using netperf  
I reach 4GBit/s between two nodes
using OFED version 1.2.51 and 3GBit/s using OFED version 1.1 (10 Gig  
Mellanox cards)  is their any parameters to apply for
improving the performance or is their any document around.

I am running OFED version 1.1 on sles 9 using kernel 2.6.5-7.283, I  
tried to to create rpm with version 1.2.51
but it fails with conflict error, the same situation with version  
1.2.5 and 1.2.0 (check below)
