Our iSCSI benchmarks on a large 80-core system show that previous limit of 8 threads can be a bottleneck. At some points this change increases write IOPS by as much as 50%. I am still not sure that so many threads is really required, but we tested lower amounts and got no significant benefits, while latencies were a bit worse, so decided to not diverge.
