What ext3 journaling options are enabled (e.g. what does

If it's data=ordered (the default), that's OK. If it's data=journal,
then all the data gets written twice (first to the journal, then the
journal to the disk), which is really really slow, and the size of the
journal would really make a difference too.
For an NFS server (assuming that you aren't exporting as async)
data=journal can give you better performance than anything else
actually. The NFS howto has a brief note in the performance section
about this.
