#513 recycle operation pblocks
Closed: Fixed None Opened 7 years ago by rmeggins.

connection_activity calls connection_make_new_pb and add_pb when there is a new operation, then connection_threadmain calls slapi_pblock_destroy - there is a lot of malloc/free here - once for the slapi_pblock, once for the struct Slapi_PBlock_q used to add it to the queue, and once for the pb_op operation_new - malloc/free is a performance bottleneck as well as a source of thread contention - instead, pre-allocate pblock/operation structures and use a lock-free stack or other lock free structure to hold unused pblocks/operations - use memset to clean the memory when the operation is complete
