annotations
[ https://issues.apache.org/jira/browse/DISPATCH-1389?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16975044#comment-16975044 ]

------------------------------------------
All the changes made against this JIRA were already released in 1.9.0. If there are further changes to make there ought to be a new Jira for them.

> Key: DISPATCH-1389

> Issue Type: Improvement
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Major

> Parsing message annotations, especially on the inter router incoming link, are quite expensive.
> For example, in a simple standalone router test the time it takes on average (on my puny laptop) to receive a message and hand it off to the core is ~1 usec:
> TestRouterA: link MyReceiver count=500000 rx=1.094
> Compare that time to the same operation performed on the inbound router link on a two-hop router configuration:
> TestRouterB: link MyReceiver count=500000 rx=7.035
> On average it's 7x slower. Most of this time appears to be spent manipulating inbound message annotations.
>
> This Jira tracks work towards improving the performance of message annotation processing.
