http://lists.debian.org/debian-amd64/2006/02/msg00005.html might be an
interesting read,
where somebody figured out that packet size 7000 was the maximum for
linerate for the 
Dell 5324.

Subject: [Beowulf] Gigabit switch recommendations

My cluster and fileservers are moving to a new home shortly, and I'm
going to take the opportunity to put them on a private network.  Given
everything is gigabit and there's a lot of NFS going on, I'd like to use
jumbo frames.  I currently have 33 systems, and I'm not likely to grow
by any huge amount (he says with uncharacteristic optimism).  So I'm
mainly looking at getting a couple of 24 port switches.

Given past research, I was about to go with the Dell 5324, but then I
came upon the much cheaper 2724.  The main differences for my purposes
seem minor (9018 byte vs. 9000 byte jumbo frame support, 8 member ports
per aggregrated link vs. 
4).  Is there any compelling reason to go with the 5324 over the 2724?
Does anyone have another recommendation in the same general price range?
