   I've just found out that adding `-Xms3000m` (probably because GC then 
doesn't need to request OS for more memory during the maven build) helps around 
4mins of total integration-tests run. So eg. from 1h10min to 1h07min. I will 
send PR for this little improvement. I'll also move TMP directory (used as java 
temp dir) to `D:\\tmp` and also move .m2/repository to `D:` disk) - even if 
doesn't speed up anything i think it is good practice to have it on the same 
(fastest) disk.
   
   And for reference, adding options like: `-Xmn750m`, 
`-XX:ParallelGCThreads=10` or `-XX:+AlwaysPreTouch` doesn't help and sometimes 
lead even to worse performance.
