Well - I'll update all my maps on Thursday again, to recheck. Maybe it
has to do with increasing-maxnodes? Though I thought the higher the
max-nodes, the faster...
And I only meant splitter. I upgraded mkgmap at the same time (now
integrating performance branch changes) - so mkgmap by itself got faster
(though it depends on the country - seems like well mapped countries
profit a lot more (e.g. Austria like 30% time off), than countries where
few continue commands will be in action cause their mapping is basic
like Asia).
I'm not using any pre-split files or cached files of any sort either...

Hi Felix,
reg. speed: I can't reproduce that. I compared a split of Germany,
both versions (r321 and r325) are more or less running the same time.
(I've executed both programs two times to make sure that disk caches
are not causing big differences)
Or did you mean the combination of splitter + mkgmap to process e.g. Asia?

Subject: Re: [mkgmap-dev] splitter r325: improved split algo and new
option
Seems to be much better now. I don't think I can increase the
max-nodes value though, but for most maps the new algo creates less
tiles for the same max-nodes value (e.g. Austria from 43 down to 35
for me, with the smallest tile now around 5MB instead of 2.8, and the
biggest 12MB instead of 11MB, for Asia I simultaneously increased
max-nodes from 800k to 900k- so I'm down from 624 tiles to 493.... and
size from 970KB-16MB to now ). So it still seems to depend on the
country, but it's already a lot better...
It's a bit slower (about 10% more time)

Hi all,
I've applied num-tiles-v1.patch and improved the split algo, see
http://gis.19327.n5.nabble.com/mkgmap-ToDo-list-tp5803388p5805165.html
It is now less likely that splitter creates tiles with a low
number of
nodes, it is more likely that all tiles have nearly the same
number of nodes,
and typically you will see fewer tiles.
Maybe this also means that you can increase the max-nodes value.
I hope this also reduces the need for complex interactions between
spltter and mkgmap.
