I'm currently running a 2008 unibody 15" MacBook Pro 2.53 with 320GB 5400 RPM hard drive and 4GB of system memory. I've upgraded to Snow Leopard and I'm running Lightroom 3 (64-bit).
I have two problems with my setup currently and I'm seeking recommendations on improving the situation:
- memory usage during processing exceeds 1.5GB
- time to move between images in Develop module is painfully slow
I've noticed that system memory usage typically goes up drastically during export to JPEG. Is this normal and how much memory is normal? It seems the larger the set of photos being exported, the greater the amount of memory is needed. I often find myself staring at Activity Monitor and shutting down all other applications to free up as much RAM as possible.
Then switching photos in the Develop module takes ages for me. I think this is a disk related issue so I'm thinking new larger 7200 RPM hard drive should sort that out. The current hard drive is a Hitachi 320GB 5400 RPM drive and it often seems to be the bottleneck when installing applications and writing data.
