Ken Giusti created DISPATCH-1389:
------------------------------------
Summary: Optimize the parsing of message annotations
Key: DISPATCH-1389
URL: https://issues.apache.org/jira/browse/DISPATCH-1389
Project: Qpid Dispatch
Issue Type: Improvement
Reporter: Ken Giusti
Assignee: Ken Giusti
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.
