The reason behind this might be that the CodeWarrior has Eclipse based IDE, and it keeps a history of changes within your workspace. Using Team > Show Local History you can compare your changes and go back and forward in history. But sometimes it slows down the IDE, especially if there are a lot of local history files. To resolve this problem, check your workspace for the size and number of files in the following folder:
.metadata\.plugins\org.eclipse.core.resources\.history
In case you notice there are lots of files, and if you are not interested in the history, or you want to limit the number of files to improve the performance, select Window > Preferences > General > Workspace > Local History (refer to the image listed below) and reduce the number (e.g. everything to 1).
This reduces the history information to the minimum every time you exit the workspace.
A more radical approach is to delete (e.g. with the Windows Explorer ) the .history folder, from the following location:
.metadata\.plugins\org.eclipse.core.resources\.history
Applying the above settings, will improve your workspace performance.
