I have a intel imac 1.83ghz processor
512MB (single SO-DIMM) 667MHz DDR2 SDRAM
Often my activity moniter says i have less than 10 mb free with memory page in/outs 320,000/210,000 is this a problem?
Would another 512mb do the trick or should i just be safe and go w/ the 1g?
What else can be done to help w/ performance?

10MB free is not big deal (since modern OSs cache disk in RAM), but hundreds of thousands of page hits is bad. I'd get another gig.

That ratio of page outs is a ton! Definitely get as much as you possibly can. My iBook with 768MB and running nine apps is only doing 55000/250

Rosetta loves RAM, anyway. More RAM can't hurt you, unless it is cheap crap.

If you have 10 mb left I would definetly ugrade. That is horrible. That is a lot of page ins/outs.

Yeah, the old Mac adage: you can never have too much RAM. It is the first upgrade you should do to any Mac. Max it out to 2Gb, or at least 1.5Gb.

bah, i say 'just make a 500 GB memory chip and be done with it!'... at the rate of which Macs (and computers in general..................... and their uses) are evolving, 500 GB for -RAM- probably would sound mediocre within 10 years anyway. 
btw, gambo... with respect to your question, if your wallet permits, go for broke and max-out that Mac!

I have the same system as the OP, but with 1.5 GB RAM. My activity monitor says I have 516 MB inactive RAM, 257 MB active RAM, 616 MB Free RAM, and 59689/0 page ins/outs. Thats with AM, quicktime, safari, mail, itunes, FileShare, and adium open.

I have a MBP with that same processor, and the RAM is identical. That said I upped it to 1 GB, with every intent of getting 2 GB once money permits, and I'm showing 43,000/0 Page in/out. Thats with Pages, iMovie, Photoshop, Safari, iTunes, and Quicktime for good measure.
Seems like the 0 Page outs is odd. Any explinations? (Honestly I'm not even sure what this measures except in very general terms).
Yous should ALWAYS uprgrade your RAM when possible. OS X devours RAM.

What exactly is page in/outs? My Ibook G4 with 512 MB of RAM is reading about 60 MB of free space open with about 90000/80000 page in/outs.

page out is the system running OUT of real ram, and swapping of data to the HDD.... "thrashing" as it sometimes referred to 
>>2000 page outs = crappy performance = you need more REAL ram
page ins are not to worry about though, all normal ops there

Thrashing is excessive paging, not merely paging.

500GB of RAM? 10 years? Isn't that minimum requirement for running Windows Vista?
