There are 517 threads in the zfs_write code path, so there seems to be
a fair amount of write activity happening.
The server iostat and zpool iostat data would be interesting, along with
the backend storage configuration information - how many spindles, and
what kind of zpool config...

Hello, gurus
I need your help. During the benchmark test of NFS-shared ZFS file systems at
some moment the number of NFS threads jumps to the maximal value, 1027
(NFSD_SERVERS was set to 1024). The latency also grows and the number of IOPS
is going down.
I've collected the output of
echo "::pgrep nfsd | ::walk thread | ::findstack -v" | mdb -k
that can be seen here:

Could you please look at it and tell me what's wrong with my NFS server.
Appreciate,
