Hi all...
I have noticed that NFS is very slow on writes with 2.4.26-pre6. Some example:
- On the server: annwn:~> time -p dd if=/dev/zero of=tst bs=1024 count=2048 2048+0 records in 2048+0 records out real 0.04 user 0.01 sys 0.04
-On the client: 2048+0 records in 2048+0 records out real 21.56 user 0.00 sys 0.02
Any idea on what's happening ?
SERVER /etc/exports: /home *.net1.cluster(rw,no_root_squash,no_subtree_check,no_auth_nlm) annwn:~> ifconfig eth2 eth2 Link encap:Ethernet HWaddr 00:03:47:23:D5:74 inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:225214 errors:0 dropped:0 overruns:0 frame:0 TX packets:135234 errors:0 dropped:0 overruns:0 carrier:134665 collisions:0 txqueuelen:1000 RX bytes:36314498 (34.6 Mb) TX bytes:47083712 (44.9 Mb) Memory:df000000-df020000 03:01.0 Ethernet controller: Intel Corp. 82543GC Gigabit Ethernet Controller (Copper) (rev 02)

Are this expected timings, or something is really wrong ?
TIA
