I can't figure out why this might be the case, but it would appear that
when unfsd is bound to a custom port and not registered with portmap,
the performance is massively improved.
I changed my init.d/unfsd script as follows, in the start option:
- /usr/sbin/unfsd -i ${pidfile}
+ /usr/sbin/unfsd -e /etc/uexports -i ${pidfile} -m 12049 -n 12049 -p
cat /etc/uexports
/home 10.2.0.0/16(rw,insecure)
On the client side I am mounting with:
server:/home /home nfs
defaults,nolock,hard,noatime,proto=udp,rsize=32768,wsize=32768,port=12049,mountport=12049
0 0
All of the horrible latency and laggyness is completely gone! Could it
be that it is unfsd's interraction with rpc/portmap/mountd that is the
cause of a lot of the performance issues?
I only did this to improve the performance of my non-glfs exports by
running knfsd for those, and only running unfsd for the glfs exports,
but this speed boost is quite a boon. :)
Note: know for a fact that knfsd isn't exporting the glfs mounted /home
because I'm not using the patched fuse kernel module that allows nfs
exports, even if the fact that /home wasn't listed in /etc/exports
wasn't enough (using /etc/uexports for unfsd, as per the startup option).
Can anybody confirm similar behaviour on their setup?
