Hell,

I already tested this and it gives the expected answer :

Outside HTCondor, the software runs very well on 1 thread per core (so 8
threads). I understand that HTCondor will add some overhead (that I hope
will be regained when scalling to multiple machines) but I really thinks
something is going wrong outside of that overhead...

For information, I'm running version 8.4.3 on a Win7 64 bits platform :

C:\Data\test_condor>condor_version
$CondorVersion: 8.4.3 Dec 15 2015 BuildID: 352143 $
$CondorPlatform: x86_64_Windows7 $
