issue-443: Increase the number of objects transferred between thread cache and central free list
This fix is a result of a performance degradation observed in multi-threaded programs where large amounts of memory (30GB) are consumed, released by a pool of threads in a cyclic manner. This was mainly due to the amount of time we were spending in the slow path consolidating memory between the thread cache and central free list. The default has been bumped up to 32768 and is now also controllable through the TCMALLOC_TRANSFER_NUM_OBJ environment setting. git-svn-id: http://gperftools.googlecode.com/svn/trunk@193 6b5cf1ce-ec42-a296-1ba9-69fdba395a50
