>From my experience tuning on a 550MHz P3 Xeon, you're better off using a 
buffer size of 8-16KB that stays in the L1 cache.  Of course, that was 
without actually doing anything useful with the data being transferred.  
Gige really does need a faster cpu in the ghz+ range.  As for ns83820, 
it's a work in progress.  Some of the recent bugfixes may have reduced 
performance, so it may need to be retuned.
