In my experience not all GigE switches are equal. I had a no-name
brand GigE switch that would choke once you tried to push any more than
30MB/s between machines (the only two on the switch). I replaced that
with a 5 port Netgear and could benchmark 100MB/s over NFS with no other
changes. Down the track I started getting networking issues that
appeared to be packet drops under load and after trying a few NIC
changes was about to blame my home cabling job until I thought to take
the switch out of the mix. Somehow the switch was dropping packets but
being unmanaged I had no stats to tell me that other than what appeared
on the hosts.
TL;DR - buy a decent quality switch, managed if you can afford it.
