Please mention which kernel do you use - there have been patches
related to discard on thin volumes (pretty resent - kernel 3.14 I think).

If you use old stable 3.10  from vanilla kernel it simply cannot be compared 
with 3.10  RHEL kernel -  they are very different (RHEL has ton of stuff 
backported even from the latest kernels)

So - please try first with upstream to see if you problem is not already fixed.
