Thanking everyone in advance. > There are many improvements in FreeBSD 6 over 4, specially for new hardware and SMP systems (multi cpu or dual core cpus). If you have an old machine, which is not connected to an external network then there probably inst any good reason to upgrade, but i would consider it in the near future, as official support for 4.x has been dropped. I cant say what code you need to rewrite, as i don't know what application you are using.
