H A D	svc_generic.c	diff b563304c Sun Jun 08 11:19:32 GMT 2014 Alexander Motin <mav@FreeBSD.org> Split RPC pool threads into number of smaller semi-isolated groups. Old design with unified thread pool was good from the point of thread utilization. But single pool-wide mutex became huge congestion point for systems with many CPUs. To reduce the congestion create several thread groups within a pool (one group for every 6 CPUs and 12 threads), each group with own mutex. Each connection during its registration is assigned to one of the groups in round-robin fashion. File affinify code may still move requests between the groups, but otherwise groups are self-contained.
