So I guess optimizing the maprenderer itself will not deliver huge improvements itself any more.
I am currently trying to get more effect from disabling the animated tiles,
which currently only boosts the background layer rendering .
I think when the foreground also gets some prerendering, the speedup is ok.
Once my raspberry arrives, I'll definitely check it on that device :)
