[mkgmap-dev] Performance of POI search on the Device

From Gerd Petermann gpetermann_muenchen at hotmail.com on Tue Jun 2 10:18:04 BST 2020

Hi Franco,

I tried your two maps and the saerch with the "good" one is indeed much faster, but still also slower than the search with just one map.
I tried to produce my own overlay map to reproduce the results but it never shows such a big impact. My map contains only cycle routes for Germany and the gmapsupp is much smaller. I tried different draw-priorities, different types in the map, with/without index.
No more time today, I'll try other things tomorrow...

Hi Gerd,
probabally I tried the "route" and "index" options with the patched version
to see if it helps. (it didn't)
I just tried the default center-POI type and 0x3200 - made no difference.

I can do further testing in the evening.
