OK, r3808 solves the performance problem in ShapeMergeFilter.

Hi Ticker,

the performance problem with that special style is in ShapeMergeFilter.
I think the reason is that the new code in MapSplitter etc. puts a lot more 
shapes into one sub div, esp. at low resolutions, and ShapeMergeFilter
doesn't work well in that case as it starts to do lots of seq. seaches.
I'll try to find a better solution for that.

Hi Gerd

Yes - use the patch

Still not sure why there is a change in performance here though.

Hi Arndt,

good to know. The patch filter-early-v1.patch  will probably further improve 
run time for you.
I'll try this tomorrow.
