FreeBSD anyone?

Hi, im running freeradius 1.0.5 + postgres 8.0.3 on a dual xeon, gentoo 2005.1, all is working ok, but i have another server with the same hardware specs that i recently "upgraded" from gentoo to freebsd 5.3, the server was running apache + postgres and, wow , great diference, better performance, so postgres definitely liked freebsd, what about freeradius?, i have read on the website that it is developed on debian but it compiles on freebsd, what is your experience with freebsd , good?, bad? , any gotchas?. Should i migrate to freebsd or stay with gentoo?, my personal preference is bsd, but im worried of any obscure future that only works on linux api's ,etc thanks in advance, Miguel
