Remove extra assertions in mutexes. > Remove performance problems from locks and memory allocation > ------------------------------------------------------------ > > Key: DISPATCH-511 > URL: https://issues.apache.org/jira/browse/DISPATCH-511 > Project: Qpid Dispatch > Issue Type: Improvement > Components: Container > Reporter: Ted Ross > Assignee: Ted Ross > Fix For: 0.7.0 > > > There are a number of performance issues with locks and memory pooling: > - Locks are not allocated on cache-line boundaries and suffer from > false-sharing issues. > - The extra lock checks (checking the acquired state) cause significant > overhead. These should be removed. > - Pooled memory objects are not cache-line aligned and suffer from > false-sharing > - Memory pool statistics are useful but costly from a performance > standpoint. These should be able to be optionally disabled. -- 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
