Alex Rudyy reopened QPID-7453: ------------------------------ Assignee: Alex Rudyy (was: Keith Wall) Reopening the JIRA as changed committed under revision [https://svn.apache.org/r1763765] cause performance degradation on 20-25% in perf test "transient_transaction_plain" > [Java Broker] Hand off selection task only if connection tasks need to be > processed > ----------------------------------------------------------------------------------- > > Key: QPID-7453 > URL: https://issues.apache.org/jira/browse/QPID-7453 > Project: Qpid > Issue Type: Improvement > Components: Java Broker > Reporter: Keith Wall > Assignee: Alex Rudyy > Fix For: qpid-java-6.1 > > > Currently the selector thread always reschedules the selection task on the > workQueue. In the case where the select was awoken for the purpose of > reregistering a connection on the selector, there will be no connection work > to be done, so the potential hand off to of the selection task will be > needless. > We can simply optimise the algorithm to hand off responsibility for the > selection iff there is connection work that can be consumed by this thread. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
