How long have you been a user of FreeBSD? Did you used to use Linux? I'm not being mean or an ass or anything, but FreeBSD handles memory management a bit different, that's the only reason why I ask. FreeBSD tends to keep as much loaded into main memory as possible, and gets rid of it when it needs more memory (either via swap, or just plain getting rid of it if no longer needed). So, I really wouldn't concern myself so much.

Of course, anyone is free to come along and prove me wrong.

"Free" RAM is wasted RAM. FreeBSD caches everything that gets read to or written from harddrives in RAM, in case the data needs to be read again. The VM system in FreeBSD also tries not to swap things out to disk unless absolutely necessary (compared to Linux where it swaps things out quite often). If an app needs more RAM, memory in the cache is freed for use by the app.

IOW, unless your system is using a lot of swap, everything is running correctly.

Note: Please tone down the obscenities. They do not make you look smart or professional, and make people not want to read your messages. You'll get a lot more (and faster, and better) responses without them.

ive been a linux user for quite some time.. ive used multiple distros such a debian, ubuntu, redhat, and fedora... and backtrack. but backtrack was a short experience. Ive also never added any monitoring applets to those operating systems till now, when i decided to test out BSD. so it caught me off guard... but i guess thats part of the server side package of BSD. thanks for the conformation guys.. i now know nothin is wrong... not that anything should be... its bsd =D

Coincidentally, yesterday I explained the memory management under *nix to a Windoze techie guy , and I did say "Free RAM is wasted RAM" too

Actually, it's in the FreeBSD FAQ. (I will freely grant that the FAQ is long and not that easy to navigate.)
Maybe we ought to put up a little FAQ for those coming from Linux.
That's one question.
The fact that md5sum is called md5 in FreeBSD.
For those coming from Ubuntu, a brief explanation of how FreeBSD handles sudo. (For those coming from Fedora, mention of su and wheel wouldn't hurt either.)
ifconfig syntax is a wee bit different.
Just a few ideas. I cover a bit of it in an old page of mine, but that page is dated.
