I think this is showing that OS X has some serious problems with memory management? And this has a significant impact on system performance. iPhoto was way slower to start and way less responsive the second time I launched it, even though the system state was effectively the same as the first...
Here's a test I did to illustrate the problem. I collected memory usage stats at different points after reboot and starting/closing apps. This seems to show:
1) After starting and quitting a bunch of apps, OS X converts a lot of memory to the Inactive Type
2) OS X doesn't seem to reclaim...
Sorry, that was the wrong link. The one that probably applies to you more is:

3 beeps after booting up = problems found with RAM at runtime. Doesn't narrow down which bank(s) are faulty though.
You do have bad RAM, from the sounds of it. Beeping like that are typically POST failures, and in this case three beeps relates to bad RAM.

Have you installed aftermarket RAM? Macs tend to be a lot more fussy about RAM quality than PCs (which just crash...
This isn't the only thread to talk about this stuff; there's been jillions, though none I've found that talks about exactly what I'm discussing, mostly just people talking about what the different "forms" of memory are.
I notice that this thread...
So I've been concerned about Mac memory management for a while.
I've had 4GB of RAM on a number of different systems with 10.5-10.7. I have 8GB at work.
I'm constantly running out of memory and paging, though. It seems like Mac OS X doesn't release memory once used. For example, if I...
Old thread, just wanted to mention something in case someone stumbles onto this thread like I did.
Oplocks have **nothing** to do with file locking. They're just really unfortunately named. They have to do with the server letting the client know whether or not it is the only system that has...
I definitely didn't expect an iPhone. I WAS hoping for something that was a little more intriguing to me, and an unexected product announcement. After all the silence lately, I guess we were hoping for something interesting to be announced.
Mac Pro and Xserve were pretty much exactly what...
My biggest complaint about iPhoto (even '06) is just the speed. It's so sluggish to work through, even on my 2.0Ghz G5 (the 1.42Ghz G4 Mini is much worse), I get tired of watching it take 1-5 seconds to load new pictures. Picasa just plain has iPhoto beat here, hands-down...It's ridiculously...
