XCode becomes almost unusable after I use it for a while. Moving the cursor, resizing the window, etc. all take way too long. When I first open it (which opens quite quickly, actually), Activity Monitor shows it as using 100-120MB of memory and XCode works great. When I first start using it, this jumps to about 300MB but I barely notice a difference in performance. All well and good. However, this number increases over time, getting to over 1GB of memory used (haven't kept it open past that, because it becomes to slow to use). I have one project open. I have no more than 5 files "open" at a time (i.e. available in the editor pane's file history drop down select) and I use the all-in-one layout, so I only have one window open. Using other layouts doesn't effect the issue. Also, having other application's open or not makes no difference.
Whenever I switch spaces (I keep XCode in its own space) to, say, use Safari and come back, XCode seems to use a little more memory. After little code changes (less than 20 lines added/modified) and several saves and build/runs, XCode keeps using more and more memory. I have garabase collection for the compiler set in the build tab of the project settings.
I've seen other people ask about this on forums and such, and the only "solutions" I've seen are to keep less projects/windows open (which is impossible, as I have bare minimum), clean your targets (which doesn't help), and close/restart XCode (which does help, temporarily, but is not a solution nor should it be necessary).
What could XCode be keeping in memory and is there a way to free some? Are these memory leaks in XCode? Does anyone else experience this slow down?
I'm on a MacBook (not Pro, but it is metal, got it Christmas 2008) running 10.6.2 with 2GB memory and a 2.4 GHz Intel Core 2 Duo, running XCode 3.2.1 64-bit. Perhaps the 64-bit part is the issue? (Though, according to Activity Monitor, most of my running apps are 64-bit). _______________________________________________
