Ken Giusti created DISPATCH-2222:
------------------------------------
Summary: Avoid cpu-intensive message string-ify of every received
AMQP message
Key: DISPATCH-2222
URL: https://issues.apache.org/jira/browse/DISPATCH-2222
Project: Qpid Dispatch
Issue Type: Bug
Components: Router Node
Affects Versions: 1.17.0
Reporter: Ken Giusti
Assignee: Ken Giusti
A call to log_link_message() is made for every received AMQP message. This
function logs a string-ified version of the message at level QD_LOG_TRACE.
log_link_message() parses out each message and summarizes it into a string
buffer before logging. This stringify operation is cpu-intensive. According
to flamegraphs it occupies 5% of the compute budget.
The string-ify operation should be avoided if the message log level doe not
have TRACE enabled.
