[mkgmap-dev] Map redraw speed

Sat Jan 16 18:17:28 GMT 2010

While, we're in the Baltic, I should tell you this:

Markus sent me a sample of the Baltic map that had been created by
someone else by converting from OSM to MP and then processing it with
cgpsmapper. It looks nice but one thing I noticed is that the redraw
speed (in mapsource) is terrible. For the same area, the mkgmap
generated map redraws in 1/2 second or less but the cgpsmapper
generated map is taking at least 2 (maybe 3) seconds to redraw when
scrolled. The .img file doesn't look particularly big so I don't know
what the problem is (but it's not our problem!)

Cheers,

Mark
