[jira] [Commented] (CAMEL-16279) camel-core - Optimize routing engine to reuse internal state objects for GC reduction

    [ https://issues.apache.org/jira/browse/CAMEL-16279?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17293001#comment-17293001 ] 

Claus Ibsen commented on CAMEL-16279:
-------------------------------------

Did a little basic example (all internal components) with timer 1000 msg/sec doing 10 steps to log:off. About 90% is objects from internal routing engine.

> If we use pooled exchanges, then we can try to experiment with storing the nessasary internal objects used during routing on the exchange (in some new place) so the routing engine can reuse these objects without cause object allocations.
> This makes memory usage more stable and reduces the GC.
