file writing over nfs very slow

Hi guys,
I am trying something. I wrote a simple shell program to test something where continuous while loop writes on a file over the nfs. The time taken to write "hello" 3000 times take about 10 sec which is not right. Ideally it should take fraction of seconds. If I write on the local disk, it happens instantaneously. "dd" command works fine over the network. Not sure if it is doing the same thing as filw writing with a shell script.
Can someone suggest me where to look at if it is NFS issue?

Thanks,
Abhi.

Post your code. If you're reopening the file 3000 times, that has overhead.
