Summary: Save qdr_error_t allocation if not necessary Key: DISPATCH-1348 URL: https://issues.apache.org/jira/browse/DISPATCH-1348 Project: Qpid Dispatch Issue Type: Improvement Components: Routing Engine Affects Versions: 1.7.0 Reporter: Francesco Nigro qdr_error_from_pn on error.c is allocating qdr_error_t on the hot path ie AMQP_disposition_handler: saving those allocations would reduce CPU usage (and cache misses) on both core and worker threads, making the router able to scale better while under load. Initial tests has shown some improvements under load (ie with core CPU thread ~97%): 5 pairs with master - 490 K msg/sec 5 pairs with new version - 530 K msg/sec -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
