> Components: runner-core
> Reporter: Steve Niemitz
> Assignee: Steve Niemitz
> Priority: Minor
> Fix For: 2.14.0

> I've noticed that for jobs that access state frequently, a percent or two of
> overall CPU time is actually spent calculating the state namespace name.
> StateNamespaces.java uses a String.format for the window namespaces, but
> could simply use a string concatenation to do the same thing with much less
> overhead.
