I would say move to 6.3R as its a better release with a lot of bug 
fixes.  In terms of your general performance issues, choice of 
hardware really makes a difference as quality of drivers can be an 
issue.  You might have a really awesome controller that works well on 
Windows or LINUX, but does not do so well under FreeBSD because there 
isnt any good driver support for it.

Did you do a fresh install or did you try and migrate from RELENG_4 
to RELENG_6 ?  What network card are you using ? What are the errors 
(CRC?).  How about a dmesg from the box.
