> Key: TAP5-2335
> URL: https://issues.apache.org/jira/browse/TAP5-2335
> Project: Tapestry 5
> Issue Type: Improvement
> Reporter: Michael Mikhulya
> Attachments:
> 0001-TAP5-2335-Decrease-number-of-operations-with-HashMap.patch
>
>
> During profiling of tapestry framework I found that HashMap is actively used
> in following code:
> {code:title=NamedSet.java}
> public void eachValue(Worker<T> worker)
> {
> F.flow(getValues()).each(worker);
> }
> {code}
> Here HashSet (which internally uses HashMap) is created inside getValues()
> only to iterate over it.
> I changed code to use ArrayList instead of HashSet.
> With following patch time per request decreased on 3.5 ms (7.4% of overall
> time). Measurements were done with apache benchmark on a real application
> after warm up phase.
