[osmosis-dev] call osmosis from groovy

[Brett Henderson]

Hi Ruediger,

8000 threads!  That's impressive :-)

Unfortunately there's not much you can do about it.  Osmosis will use one
thread per xml reader, and one thread per merge task.  It's probably
possible to develop a more efficient implementation but your use case sounds
fairly unusual.  If it won't run properly with 8000 threads you could try
running Osmosis in several passes by combining smaller sets together then
combining merged files into larger merged files.

Cheers,
Brett
