When the knfsd bottom half\nis made aware of an incoming call by the socket layer, it tries to\nchoose an nfsd thread and wake it up. As long as there are idle\nthreads, one will be woken up.\n\nIf there are lot of nfsd threads (a sensible configuration when\nthe server is disk-bound or is running an HSM), there will be many\nmore nfsd threads than CPUs to run them. Under a high call-rate\nlow service-time workload, the result is that almost every nfsd is\nrunnable, but only a handful are actually able to run. This situation\ncauses two significant problems:\n\n1. The CPU scheduler takes over 10% of each CPU, which is robbing\n the nfsd threads of valuable CPU time.\n\n2. At a high enough load, the nfsd threads starve userspace threads\n of CPU time, to the point where daemons like portmap and rpc.mountd\n do not schedule for tens of seconds at a time. Clients attempting\n to mount an NFS filesystem timeout at the very first step (opening\n a TCP connection to portmap) because portmap cannot wake up from\n select() and call accept() in time.\n\nDisclaimer: these effects were observed on a SLES9 kernel, modern\nkernels\u0027 schedulers may behave more gracefully.\n\nThe solution is simple: keep in each svc_pool a counter of the number\nof threads which have been woken but have not yet run, and do not wake\nany more if that count reaches an arbitrary small threshold.\n\nTesting was on a 4 CPU 4 NIC Altix using 4 IRIX clients, each with 16\nsynthetic client threads simulating an rsync (i.e. recursive directory\nlisting) workload reading from an i386 RH9 install image (161480\nregular files in 10841 directories) on the server. That tree is small\nenough to fill in the server\u0027s RAM so no disk traffic was involved.\nThis setup gives a sustained call rate in excess of 60000 calls/sec\nbefore being CPU-bound on the server. The server was running 128 nfsds.\n\nProfiling showed schedule() taking 6.7% of every CPU, and __wake_up()\ntaking 5.2%. This patch drops those contributions to 3.0% and 2.2%.\nLoad average was over 120 before the patch, and 20.9 after.\n\nThis patch is a forward-ported version of knfsd-avoid-nfsd-overload\nwhich has been shipping in the SGI \"Enhanced NFS\" product since 2006.\nIt has been posted before:\n\nhttp://article.gmane.org/gmane.linux.nfs/10374\n\nSigned-off-by: Greg Banks \u003cgnb@sgi.com\u003e\nSigned-off-by: J.
