After using Eclipse Indigo for around a year, suddenly the speed of an application ran in Eclipse has decreased intensely. For example, my Java game was getting 64 FPS, then suddenly 1 FPS.
Creating a new Workspace and adding all the files from the old project seems to fix it, but how would I fix this without making a new Workspace? (I’ve already tried deleting the Workspace’s .metadata, made no difference.)
I’ve also tried running Eclipse with the -clean argument, no help at all.
Note that the performance issues are only when running a Java Application from Eclipse, not within Eclipse itself.
My guess is that eclipse is stuck doing background work, and causing your PC to run out of resources, resulting in paging. Also have you installed any new plugins recently? Some plugins can conflict with each other which could be an issue. Check task manager to see where your resources are at while the game is running, then go from there.
Another issue I’ve seen is too many separate projects in 1 workspace. Is your game the only project in your slow eclipse workspace? If not,dedicating a workspace to individual groups of projects can help.
