Recently I've been using my 2010 MacBook Pro extensively with Lightroom, finding the performance ok-could-be-better, which got me thinking how to improve it. The laptop has the standard 4gb of RAM, so obviously one option is to increase that to 8 - but will it make a difference?
Before everyone shouts "yes, you fool" ... I've installed iStat on the machine, which toolbar graphs for things like CPU and memory usage. What's clear from watching the info is that Lightroom rarely uses more than 1gb of RAM, and there is often 40-50% of total memory free. On that basis I'm wondering if adding more RAM would just give me more free memory, which isn't worth paying for, or if Lightroom would start using more memory because there is more available.
