> small performance improvement from inling one fn.
> -------------------------------------------------
>
> Key: PROTON-700
> URL: https://issues.apache.org/jira/browse/PROTON-700
> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-c
> Reporter: michael goulish
> Assignee: michael goulish
> Priority: Minor
>
> inlining the internal function pn_data_node() improves speed somewhere
> between 2.6% and 6%, depending on architecture.
> This is based on testing I did with two C-based clients written at the engine
> interface level.
> The higher 6% figure was seen on a more modern machine with recent Intel
> processors, the lower figure was seen on an older box with AMD processors.
> But the effect is real: after 5- repetition before the change & 50 after,
> T-test indicates odds of this happening by chance is 2.0e-18 .
