--- Comment #2 from Jason W. Bacon <jwb at freebsd.org> ---
Thanks for the suggestions.  I disabled intr and I'm still getting variable
results.

Server and clients are all FreeBSD 12.1 and I am not using nfsuserd.

Server:

vfs.zfs.min_auto_ashift=12
net.inet.icmp.drop_redirect=1
net.inet.ip.sourceroute=0
net.inet.ip.accept_sourceroute=0
net.inet.tcp.rfc1323=0
vfs.nfs.enable_uidtostring=1
vfs.nfsd.enable_stringtouid=1
vfs.nfsd.tcphighwater=20000
vfs.nfsd.tcpcachetimeo=3600

Clients:

vfs.nfs.enable_uidtostring=1

Happy to try other suggestions if you have any.
