I set up one NFS server, and mounted on other server by TCP. Servers
connected with Giga network, and running 6.2-RELEASE.
But I found the performance is very bad while transfering large block size data.
For example, I use dd on NFS client to test the speed.
And ``systat -vm 1'' is displayed HDD is most busy,
Disks da0
KB/t 16.00
tps 239
MB/s 3.73
% busy 91
Can I do some tuning to improve large block size transfer over NFS?
Try adding read- and write-size 32768, partial /etc/fstab:
rw,intr,nfsv3,-a=4,-w=32768,-r=32768
or adding -r 32768 -w 32768 while mounting from command line.
