Which benchmark?
Which HCA?
Is it the same with ofed beta release?
Hi,
I'd like to note that this performance problem seems still to exist in
OFED
1.3rc1.
On our testing environment (2 Hosts, Xeon 3040, Mellanox MT25208 HCA) with
OFED 1.3rc1 on Fedora 8/Kernel 2.6.23.9-rc1, ib_rdma_bw yields a bandwidth
of 658 MB/sec with a one megabyte message size. Other benchmarks show
similar results.

Hi,
I've checked this issue on 4 x Intel(R) Xeon(R) CPU 5130 @ 2.00GHz
with
SLES10
MT25208 HCA
FW 4.8.200
OFED 1.3-20071211-0600
and I got 935.68 MBps.
