[Gluster-users] Single-thread read/write performance over TCP/IP?

Hello. I have a fairly simple question.
What is the fastest single-client, single-thread, single-file read
performance anyone has ever observed using GlusterFS over TCP/IP, and
what hardware did it use?
I need to be able to read 500 megabytes/second, sustained, from a
single file using a single thread. I have achieved such speeds and
higher, reading 200+ gigabytes sequentially, using a fast RAID and XFS
(i.e., local storage). I would like to replace that design with
something more networked and scalable. But my individual clients
still require 500+ megabyte/second reads.
If I tie together a half dozen fast GlusterFS servers with 10GigE,
will I be able to serve another half dozen 10GigE clients at 500MB/sec
each? (Again, assuming single-file, single-thread on each client.
Also assume each server can read/write its local store at ~1000 MB/sec
sustained.)
Finally, and perhaps off-topic for this list... If Gluster cannot do
this sort of thing, are there any distributed Linux file systems that
can?
Thanks.

P.S. Yes, I sent a similar message to the PVFS2 list. Apologies to
those on both lists who are seeing it twice.
