Description

I ran out of heap space when running on 1300 stations with standard settings. Looking at earlier tickets, I noticed that most people are running with -Xmx768m. I tested with some smaller sets using visualvm, and got these results:

Num Stations Max Heap Usage
200 103M
500 213M
1300 431M

Extrapolating, 768m should allow processing of about 2500 stations.

I think the wiki pages should include at least a suggestion to use -Xmx768m.
