Sometimes end users experience a slow down of the Lotus Notes client.
Compacting the Lotus Notes application files and Workspace improves the efficiency of Lotus Notes.
Also removing the Lotus Notes Cashfile (Cash.ndk) helps to improve the performance
In my opinion this should not be an end user task. Therefor I propose the following idea:
1) a button (called e.g. performance booster) that does all thes tasks automatically.
2) a scheduled automated way that performes these tasks automatically.
