--------------------------------------
Summary: Decrease number of operations with HashMap #1
Key: TAP5-2334
URL: https://issues.apache.org/jira/browse/TAP5-2334
Project: Tapestry 5
Issue Type: Improvement
Reporter: Michael Mikhulya
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.
