Run the profiler.

I know that System.gc() is needless and discouraged, and I don't try
to suggest otherwise, but the point is that it shouldn't cause issues
either (i.e. it should be useless at most).

If I add the following code to my Activity.onPause(), then my
application will be slow after the second start of the activity:

if (isFinishing()) {
    System.gc();
}

I.e. the framerate in my GLSurfaceView will be reduced by 50%. If I
remove the System.gc() call, everything is totally fine, no matter how
many times I start the activity again (i.e. start it again after it
was finished()).

The relevant source codes here:

Please help! GC is discouraged but shouldn't mess up the View/Layout
destroying system of Android.
