I mention duplex as a suspect as mismatches cause these sorts of
issues, but also half-duplex means collisions of data (especially
when there is high data throughput on that interface) which can
lead to the symptoms. ifconfig on most OSes should tell you what
speed has been negotiated (or mii-tool on linux boxes, Solaris is
a bit more complicated take a look at:

http://www.brandonhutchinson.com/Solaris_NIC_speed_and_duplex_settings.html).

Also netstat -ni will give you interface stats about errors and collisions.
