Hi all, after some double checks and test I still have CentOS nfs
client performance not exciting... Just for the record nfs server is
Solaris 10. With CentOs client I reach at most ~ 80 MB/s on a gigabit
ethernet... I should be satisfied, as it is close to real-world
ethernet performance. Nevertheless I have ~100 MB/s with other linux
clients (not CentOS). The mount options are the same on CentOS and on
Gentoo...
rw
,nosuid
,vers
=
3
,rsize
=1048576,wsize=1048576,hard,noacl,proto=tcp,timeo=600,retrans=2,sec=sys
Also, I've tried another NFS server based on FreeBSD
rw
,vers
=3,rsize=32768,wsize=32768,hard,proto=tcp,timeo=600,retrans=2,sec=sys
(options are results of nfsstat -m).
I have ~74 MB/s on Gentoo and 52 MB/s on CentOS...
I've tried many wsize/rsize, a bunch of different mount options, but
still I can't outperform those values...
