Just upgraded to Snow Leopard on a 27" iMAC and LR seems to be very sluggish with lots of spinning rainbows? Activity monitor show at times LR using 170-80% of CPU.
Anyone else notice this when moving to Snow Leopard?
Is this normal? I expected better performance when moving from my 20" iMAC with 3g of RAM.
Had a similar problem when I moved to the new Imac with snowleopard. I tracked the problem down to the migration assistant not doing a great job of copying the applications from the old imac to the new. I ran an install with the SL disks and seemed to fix the problem.
