I recently installed Arch64 on my MacBook and everything works fine, however I noticed its using very much RAM in comparison to my 32 bit workstation system (which has 4GB, not all seen o/c in 32 bit, while my laptop has only 2GB). Right now, with only X, musca, firefox and 3 urxvt terms open its using about 25% of it. which comes down to about 500MB. I didn't mind that much until just now I've seen it going up to 64% after I've launched matlab and it remained at this number after I closed it. My system is still responsive and fast, but I'm afraid I'm running out of RAM quite fast this way...thus if this cannot be explained or fixed I'm forced to go back to Arch32.
Is anybody else experiencing this ? I'm running kernel version 2.6.33.4-1 btw, and xorg 1.7.6-3.

Run f.e. htop and check which app(s) are using more RAM than you expect.
EditL @jwwolf - I don't think it's 1 - 500 MB is a bit low. As for 2 - it's ancient :-)

Unused RAM is wasted RAM.
And firefox is KNOWN to be a memory grubby hog.
Let the kernel do it's job. Unless you are specifically having issues(100% ram usages and high swap usage) there is little to worry about.
Also relating to Arch32 v Arch64.64 has a larger memory address(64 against 32) apps will use more RAM.

Ahh interesting, learnt something new yet again, I've just put "no_buffers yes" in conky and it gives me a much better picture of what is actually used. It's showing 11% instead of 25% now. Thanks for clarifying this for me guys !

So "X, musca, firefox and 3 urxvt terms open" costs you about 220MB RAM - absolutely normal usage, nothing out of the ordinary.
On my 32-bit Arch I get 270MB out of 1GB so you're much better off :-)
