Francesco Nigro created DISPATCH-1352:
-----------------------------------------
Summary: qd_buffer_list_clone cost is dominated by cache misses
Key: DISPATCH-1352
URL: https://issues.apache.org/jira/browse/DISPATCH-1352
Project: Qpid Dispatch
Issue Type: Improvement
Affects Versions: 1.7.0
Reporter: Francesco Nigro
qd_buffer_list_clone on qd_message_copy for
qd_message_pvt_t.ma_to_override/ma_trace/ma_ingress is dominated by cache
misses costs:
* to "allocate" new qd_buffer_t
* to reference any qd_buffer_t from the source qd_buffer_list_t
Such cost is the main reason why the core thread is having a very low IPC (< 1
istr/cycle) and given the single threaded nature of the router while dealing
with it; solving it will bring a huge performance improvement to make the
router able to scale better.
