 There are a few interesting things in this config:
 
-suppressConsoleOutputFromTests <-- set this to true if you want to see the console output from tests. 
-concurrentCopies="1" <-- if you specify this to something >1 it will load that many concurrent copies.

+Right now I set it to about 15 hours (instead of 48) because some of the tests will keep growing in memory usage. If you don't have a machine with a decent amount of memory you can change this to a smaller amount. You can always run this in a loop in a .cmd file for 48 hours:
