I have an FC2 machine, kernel 2.6.8-1.521. I am exporting a disk via NFS.
Perfomance to Linux clients seems fine. With an 'Alpha' workstation running Compaq Tru64 v5.1, performance is asymmetrical. Reading a file is fast, less than a second for a 75 MB file (got gigabit.)
# time cp /nfs/test/file.big /usr/tmp
0.000u 0.635s 0:00.64 98.4% 0+1k 1+9312io 0pf+0w
Writing to the NFS disk is much slower, 30 seconds or more:
# time cp /usr/tmp/file.big /nfs/test/
0.003u 0.613s 0:32.56 1.8% 0+1k 50+9217io 43pf+0w
What is wrong, and how can I fix it? Tru64 mounts the disk as NFSv3.
I think this problem has been around for at least a few years.
