Any time I move, copy, duplicate, add a file I get the beach ball for 2-5 seconds.... Machine: 2011 MBA w/ 4GB and 256 SSD, Lion 10.7.4 CPU: First I thought it was the CPU, but after monitoring activtity monitor for a long time its clear that its not it. I get spikes once in a while (chrome and DropBox) but nothing excessive. Memory Then I though it was some rouge program or background process. So I canceled all but a handful of my menu bar background apps. Does not seem to have any effect OS issue I reinstalled Lion and that really seemed to help a lot. I first uninstalled a bunch of files that I did not need (90 GB free now) before doing so. My issue has come back however, after about 1-2 weeks. Anyone have any potential solutions? I need to get to bottom of this, putting a damper on my workflow.. Thanks!
