Subject: [gentoo-user] NFS terribly slow on writes

1 Hi,
3 on one of our students' lab the home directories of the students are
4 mounted via NFS.
5 Our main application ( seems to write a lot of small
6 chunks to files in the
7 students' home directories.
9 Thus, just finishing Codelite takes 100 seconds while the same version
10 on a pure local machine
11 takes about 2 seconds for that.
13 A simple test
14 dd bs=80 count=10000 if=/dev/zero of=$HOME/Test
15 shows only 80 Kb/sec (speed of a floppy drive).
16 The machine was idle and connected to a dedicated, nearly idle server
17 by a network
18 of 1Gb/sec.
20 Does anybody have some hints on how to speed up such an NFS3 setup?
22 Many thanks for some clues.
24 By the way, NFS was set up with the async option.
26 Helmut.
