One of the fixes in the latest update is for faster processing with iPhoto and Aperture libraries, anybody noticed a performance difference after updating their copy of OS X?
I definitely have noticed improvements in iPhoto. The biggest improvement is from saving after I've edited a picture. There used to be a really long delay saving the full resolution. It is much quicker now.
Lucky you, I haven't noticed anything. I've given up hope for any performance improvements on a 3 year old laptop :-(. Upgrade coming soon when I get another job!
