>
>
> During profiling I found that there is a lot of work with HashMap inside
> tapestry framework.
> With following patch time per request decreased on 2.2ms (4.6% of overall
> time). Measurements were done with apache benchmark on a real application
> after warm up phase.
> The idea behind the patch is to get rid of double lookup inside HashMap (or
> event triple lookup) whenever only one lookup is enough.
> Also this patch decrease number of ThreadLocal.get calls in two times by
> moving PerThreadServiceCreator functionality into PerthreadManager.
