Our suspicion that it was needing to spawn more processes was correct. We noticed these sysctl tunables: vfs.nfsrv.minthreads: 4 vfs.nfsrv.maxthreads: 4 vfs.nfsrv.threads: 4 We manually changed vfs.nfsrv.maxthreads to 200 and now it is varying from 7 to 25 and the client delays stopped. The I compared the snapshot of 8-CURRENT and although we have 1.35 of nfsd, some of he upgrades in sys/nfsserver that is in CVS with the same comment is not on our snapshot so the issue of ignoreing -n may not be an issue with HEAD right now, but we are available to test this, sorry. Thanks!
