[mkgmap-dev] r3239 in performance2 branch

From GerdP gpetermann_muenchen at hotmail.com on Thu May 1 20:42:06 BST 2014

Hi Henning,

thanks for the info. I'll try to find out why Scandinavia and 
Patagonia don't show an improvement.
One change is related to the number of routing nodes/arcs.
The bigger the number the more CPU time is saved.
I assume in these areas other algorithms are much more
important.

Gerd
