My understanding was, stupid assuming me, that netbook2 could deliver

AFAIK only if you're using pNFS, and it has existed only briefly as a
proof of concept.
Yes that's the configuration I was talking about.
If I understand correctly, what you're basically saying is that max
throughput with above configuration is always limited to 100Mb/s no
matter how many netbooks I'm using as pvfs2 servers ?
If you're using NFS, yes. If the clients are running pvfs-client, on
the other hand, each client can talk directly to the pvfs servers,
therefore parallelizinf accesses and aggregate performance.
If I'll install another pvfs2-client, what functions beside the
pvfs2-?????? programs, are able to benefit from this?
I did compare it to an ancient pvfs2/nfs setup which runs with a
pvfs2/nfs-modified 2.6.17 kernel which resulted in the scaling I was
expecting. I could pull 2.2 -2.4Gb/s from 3 single 1Gb nodes, with
copy or rsync, don't remember exactly. I'll check it tomorrow.
Really? That's quite surprising, unless as I mentioned, it actually is
running pNFS/PVFS1.
