NFS buffering

I have an NFS buffer question,

- machine A and B are both mounting /dir from a NetApp filer.

- machine A runs an application that logs into /dir/file.log. App
  logs about 1 line every 2-3 seconds.

- From machine A, the log is available "realtime". I can tail and
  see the 1 line every 2-3 seconds.

- From machine B, the log will show up in chunks every 30-40
  seconds. If I tail, I'll get like 20 lines every 40 seconds.

Question is who is buffering.

  Is it cached for writing on the NFS client?
  Is it cached on the NFS server somehow?

Thanks for the help.

   You can lead a mule to water, but you can't make him drink.
   However, if you shoot a couple of uncooperative mules, the
   rest tend to get pretty thirsty.
