Is there a way I can uninstall Mylyn from Eclipse PDT. It comes pre-installed and I don't think I am going to use it. So I want to take all the additional plugins out of my eclipse copy as my IDE is already running sluggishly.
The uninstall process is explained in the Mylyn FAQ
We recommend uninstalling in Eclipse via the
Help → Software Updates → Manage Configuration
dialog. If you get an error message when trying to uninstall, you will need to first uninstall dependencies that use Mylyn. These include things like the Subclipse Mylyn integration and the Bugzilla Connector.You can also uninstall manually by deleting all of the Mylyn plug-ins and features from the eclipse/plugins and eclipse/features directory make sure to delete all of the plug-ins and then restart Eclipse with the
-clean
option (e.g. by inserting it into a shortcut or the eclipse.ini file.
When Mylyn is not being used (i.e., no Mylyn views open and no active task) it should not effect performance in any way. If it is causing you performance problems please file a bug, as:
The Mylyn team considers any speed or memory performance overhead from Mylyn to be a critical bug. Please file a bug report: http://eclipse.org/mylyn/support/
If you want to speedup your startup without uninstalling Mylyn, since uninstalling plugins in Eclipse can be tedious, open Window -> Preferences -> General -> Startup and Shutdown and uncheck the Mylyn features.
