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...<br>
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).<br>
<br>
I'm not using any pre-split files or cached files of any sort
either...<br>

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

Subject: Re: [mkgmap-dev] splitter r325: improved split algo
and new option<br>
<br>
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...<br>
It's a bit slower (about 10% more time) <br>

I've applied num-tiles-v1.patch and improved the split

It is now less likely that splitter creates tiles with a
low number of <br>
nodes, it is more likely that all tiles have nearly the
same number of nodes,<br>
and typically you will see fewer tiles.<br>
Maybe this also means that you can increase the max-nodes
value.<br>
<br>
I hope this also reduces the need for complex interactions
between <br>
spltter and mkgmap.<br>
