[PLUG] NFS udp vs tcp transfers
|
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Greetings
I am trying to tune NFS for my build cluster here and have some questions
with some of the options. I have been wondering what is the difference
between using udp and tcp for nfs connection reliability and speed. I am
assuming tcp is more reliable but udp is faster.
For me reliability is more important but I will take all of the speed I can
get.
My last question is about rsize and wsize, I read somewhere that if you change
it to 8k chunks you get better performance, is there an opimal value for
this? Are larger chunks better for a high latency network, such as wireless?
Are smaller chunks better for 10bT networks? Has anyone ever looked into
this?
Thanks
