By this time I found out that the BIOS of the test systems (Intel
Server Board S5000PAL) set the PCI-e parameter MaxReadReq to 128
bytes, which explains the low InfiniBand performance. After changing
this parameter to 4096 bytes the InfiniBand throughput was as
expected: ib_rdma_bw now reports a
bandwidth of 933 MB/s.
What are the new SRPT/iSER numbers?
Bart.
