mav	16b0bb1da4	Move most of NFS file handle affinity code out of the heavily congested ... global RPC thread pool lock and protect it with own set of locks. On synthetic benchmarks this improves peak NFS request rate by 40%.	2013-12-30 20:23:15 +00:00
mav	c84160c1b2	Fix RPC server threads file handle affinity to work better with ZFS. ... Instead of taking 8 specific bytes of file handle to identify file during RPC thread affitinity handling, use trivial hash of the full file handle. ZFS's struct zfid_short does not have padding field after the length field, as result, originally picked 8 bytes are loosing lower 16 bits of object ID, causing many false matches and unneeded requests affinity to same thread. This fix substantially improves NFS server latency and scalability in SPEC NFS benchmark by more flexible use of multiple NFS threads. Sponsored by: iXsystems, Inc.	2013-12-23 08:43:16 +00:00
