Francesco Nigro created DISPATCH-1371:
-----------------------------------------
Summary: qd_alloc can reuse instances in LIFO order
Key: DISPATCH-1371
URL: https://issues.apache.org/jira/browse/DISPATCH-1371
Project: Qpid Dispatch
Issue Type: Improvement
Affects Versions: 1.8.0
Reporter: Francesco Nigro
qd_dealloc is inserting instances on the tail of the thread local free_list
while qd_alloc is reading from the head, always causing cache misses unless
free_list size is 1.
qd_alloc could instead reuse the last inserted instance ie the tail, using
free_list as a stack (with LIFO accesses).
