Scanned the source code than ran the jar file. Once I finally got the file it ran under linux no questions asked. I think my network connectivity is a little 'off' on the box (compared to what linux should be) so the initial operations seemed to take forever (e.g., switching to doge in the drop-down took a number of seconds). The typical betting response is pretty quick (I'm guestimating 3 responses per second), but I'll hit a period where it'll drop for a bit (few seconds) before picking back up.

As I'm guessing this might be the machine, I ran an instance on a windows laptop and was hitting ~240 rolls per minute. Going back and clocking the linux desktop (same shared internet connection), it was averaging 175 rolls per minute (averaged over 5 minutes). Running a second instance in linux resulted in a core dump in under 2 minutes (though the initial process remained running).

Bottom line is I believe the bot code is sufficient, but my desktop could be better 

I'll be letting them run for awhile and see what happens...
