comment Need help to configure one windows and one linux server using one static ip?
It sounds like you're looking for Network Address Translation: en.wikipedia.org/wiki/Network_address_translation -- google the make/model of your router and the word "NAT".

comment Poor NFS performance when sequentially reading large files
Thanks for this. I'll conduct some experiments directly on the box to see whether the same thing happens if I read the files locally. The real point is that there's no reason for the reading to be seek-bound: I am sequentially reading a fairly small number of large files.

comment Poor NFS performance when sequentially reading large files
@sciurus: Yes, a single client reading a single file easily saturates a gig-E link. In iostat, rMB/s is in excess of 100 MB/s, and %util is about 50%. I've edited the post to include this.
