Do you guys think there is a big difference I would notice by adding more RAM to my machine.

I use Photoshop, FCP, VMware (windows 7 and XP) and all the basic apps (itunes firefox etc)

Havent done much gaming but want to now that I have my MP

would I notice a difference by adding 2 or 4 more GB in my 2 empty slots?

the most ive gotten up to is 5 or 5.5GB but if I play games in windows through VMware im wondering if that is going to suck RAM like crazy

If you have any page outs in Activity Monitor, then it is time for a RAM upgrade.
Yeah this is the best way to tell. The more page outs you get the bigger the speed boost you will get.

I know I plan on buying another 4 gb soon. Am I ever glad I got a Mac Pro. I was told by everyone here not too because I don't use pro apps. I am at 7gb of ram and I still run out.

as noted, look for page outs.

Virtual machines lock up a lot of ram.

I routinely was getting large amounts of page outs until I hit 12GB ram personally, but I leave parallels running almost constantly and have photoshop and lightroom and multiple other programs running almost constantly as well.

Please correct me if I'm wrong, but I thought that's it's ok and expected to have some Page outs, but they should be less than 10% of your number of page ins.

I've been up for 16d and have:

Page Ins: 5.3mil
Page Outs: 31,582

Nothing to worry, right?

I have 16GB of RAM and I still get page outs.

I remember someone else on MR that said he had 32GB of RAM and still gets page outs. OSX LOVES RAM!!

Says the guy with 1GB :rolleyes:

I have 12GB of RAM, have been up for 32 days and have:

Page outs: 696.00 KB

I bet I need a RAM upgrade too...

No, those are about right. I mean one can never have too much RAM of course but for 8 to 12 GB of ram that's very expected and I doubt seriously having 16GB would reduce the in/out ratio much - if at all.

I've been up for about 7 days now. I have 12GB RAM and my ratio is very similar:

vm size: 139.85 gb (huh?)
page ins: 2.86 gb
page outs: 776.3 mb
swap used 1.98 gb

page ins: 749,992
page out: 198,732

lately (since i installed snow leopard) i never see less than 120 mb free and around 1.4 gb active.
leopard likes ram, snow leopard loves ram and has an addiction.
ya i have only 2gb ddr2, and it is only a mbp not a beast of a machine you guys are running.

Well, I think it has more to do with "up-time" and of course usage. Page-outs and page-ins accumulate over time. If it's 64,000 page-outs in an uptime of 2 or 3 weeks that's phenomenal. If that's 24 hours then that's about right - again also depending on usage.

Its more the ration of page in to page outs. That way to accounts for uptime.

So can we say the following is an axiom:

Assuming several days uptime and normal use, Page Outs should be no more than 10% of the number of Page Ins.

Sound like a good philosophy?

BTW I presently have 6mil Page Ins and 51,478 Page Outs and I'm at 18d uptime.

I have 9GB of ram in my G5 and 2.9million page-outs and 4.3million page-ins after 6 days up time.
Wow dude - is adding more memory a viable option? That's the worst ratio I've seen - and it's not like you've been stingy on RAM! Is G5 architecture less efficient or something? That's crazy.
