[mkgmap-dev] MDR building out-of-memory

Tue May 11 12:27:22 BST 2021

Hi Gerd

Here is updated version of patch.

Changes from last:

Uses your cache code for region and country (in 2 places). For British
Isles, there are 190 regions and 7 countries, so I don't think the
extra memory will be a problem and there should be some performance
benefit.

Delays allocating cities until it can use sortKeys.size() for initial
allocation. For above map this is 0.07% too big, so I don't think
trimToSize() is worthwhile.

Shares the Sort object between the 4 methods.
