Aperture running at a crawl since lion upgrade

I upgraded to lion and my Mac, including aperture, is slow and pausing often. Will this improve on it's own?

Curiouser and curiouser.


Bought a spanking new 4Gb iMac, downloaded Lion from the App store and installed it. Ditto Aperture.


With Aperture running the system was unusable it was so slow and would hang but eventually allow cursor response. Switched to 32 bit mode and saw some improvement, but discovered 50+Gb page outs in a couple days of up time.


Order 8Gb more memory and installed it. Huzzah! With 12Gb, I had crisp response to everything during 6 hours of photo work in Aperture and iPhoto, and text editing in Pages while running and occasionally using Evernote, iTunes, Safari and Mail (about 6.6Gb of memory used, 5.5 free).


Left early, system idle for a few minutes and then sleeping for 15 hours. This morning, I hit the return key and system came up with Acitivity Monitor in the foreground and Aperture cranking away doing something that used ~170% of processor with nothing showing in activity window. System memory shows 1.7Mb of page outs.

Thomas, IMHO, this behavior is normal. I see this in Snow Leopard on my 12GB iMac


Aperture can go off on its own doing odd stuff, like processing RAW files with the latest RAW processor. Go to Window > Show Activity and then you can see what it's up to. Past couple of days I've been seeing a lot of this.


Also, I see amounts of Page Outs like a few megs, or even a few hundred megs if I've been working the system hard for a good while


For example right now, my system has been up for 26 hours (since last boot), and ...


VM size = 242 GB

Page Ins = 71 GB

Page Outs = 405 MB (tiny in comparison to Page Ins)

Swap Used = 31 MB


PS above numbers are rounded for clarity
