Is RAM the bottleneck in running lightroom?
I'm running on a centrino 1.5ghz laptop with 512mb of ram. I've impressed by adobe lightroom's functionality and ease of use. However, speed is rather sluggish. I see alot of rendering during thumbnail browsing as well as editing. It seems like lightroom likes to create and re-create thumbnail previews as i scroll around. Editing photos (like doing curves) also result in the photo refreshing back and forth between low and high res versions. This is really annoying.
I wonder what might be the bottleneck, and checked my ram availability as lightroom is running. While i still have 100~300mb of physical ram available, page file tends to run high at 600+mb.
My photos come from a 6mpx d70, 40% are RAWs.
I have no intention of buying a new system at the moment. If there's nothing else i can do i'd rather stick with picasa...
