[Regarding paging] You'd think that after just taking a class about Operating Systems and talking about paging, etc. I would remember. It sounds right (page out in order to page in), but I'm going to have to go look it up via my book or the Internet to confirm. 2. [Regarding mmp()] If I still had my borrowed copy of "OS X Internals", I could probably tell you. :-) Two things.

Fortunately, iPhoto 7.0.2 (upgraded yesterday afternoon) seems to be a lot steadier overall. I only got a good long hang up twice, one of which did burn through nearly 30,000 page-ins. Over the hour the page-ins have been climbing, from 476,203 to 603,869 in addition to eating up all but 68MB of 1.04GB free, so iPhoto definitely keeps a lot in memory. There were still occasional hang-ups that , but they each lasted only a second tops. Only 1 page-in during these. What's curious to me is that the page-outs only went from 127,293 to 177,263....I thought that memory had to be paged out before being paged in. Or does mmap() use the pager? An experiment for another day, I suppose... I’ve been using it for almost an hour now. Fortunately, iPhoto 7.0.2 (upgraded yesterday afternoon) seems to be a lot steadier overall.

I'll try it again, writing the starting count down first. I did look at those stats in Activity monitor, but I was still kind of groggy in the morning and wasn’t sure by how much they went up.

Otherwise, I think there are other, better ways, but I'm afraid I'm not sure what they are or how to use them.
