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. >I'm seeing signal 6's on apache and imapd (never happened before) 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. ---Mike
