[osmosis-dev] superslow completeWays again

[Maxim Dubinin]

Hi osmosis-devs,

Our server spent 54+ hours tryingn to clip Moscow region by osmosis with
completeWays on. I then spent another half a day with smaller test
region, trying to make Osmosis (0.31.2) clip with completeWays=yes in
reasonable amount of time. No luck.

Writing to the output file is very slow. According to logging, output
speed drops from 3000 to 50 nodes/sec.

Reducing the input file doesn't help at all, regardless whether I have a country
subset as input (3 gb), or pre-clipped osm file (20 mb) - it still
takes 40 mins for the test region.

I've read all I could find on the topic and I guess I'm seeking for
confirmation like "don't even try to do it with osmosis".

I hope I missed something obvious. Any pointers?

Maxim
