1 Hello,
2
3 I am running a x86 gentoo box as a nfs server. As a filesystem I am
4 using XFS on a 3ware Raid system.
5
6 The 3ware systems seems to be quite quick, although access via NFS
7 seems to be very slow. Any ideas how I can improve speed ? I was
8 expected a speed only limited by the 100 Mbit network. Now, the
9 speed is so slow, that reading/writing at the same time is nearly
10 impossible.
11
12 Any ideas how to improve the speed ?
13
14 hdparm on the gentoo box machine:
15 backup3 ~ # hdparm -tT /dev/sdb
16 /dev/sdb:
17 Timing cached reads: 4108 MB in 2.00 seconds = 2054.34 MB/sec
18 Timing buffered disk reads: 232 MB in 3.01 seconds = 77.09 MB/sec
19
20 /etc/exports on the gentoo box:
21 /mnt/backup/ 192.168.1.0/24
22 (rw,no_root_squash,async,no_subtree_check)
23
24 I am not even able to run a bonnie benchmark on the client. It seems
25 to hang while doing rewriting. Running bonnie on the nfs server
26 gives a fast result.
27
28 /etc/fstab on the client:
29 192.168.1.3:/mnt/backup /mnt/backup nfs
30 rw,users,async 0

34 Any ideas ?
