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 ?
