Michael Mikhulya commented on TAP5-2477:
----------------------------------------
We did measurements using tapestry with additional patches, see TAP5-2461 and
TAP5-2333.
Also we use tomcat with APR Connector to decrease overhead from tomcat.
Without it the gain will be much smaller (in percents).
Anyway we can attach "top consumers" from jvisualvm before and after patch.
Befor patch PerthreadManagerImpl.getPerthreadMap was the hottest one in
org.apache.tapestry package.

> return CollectionFactory.newMap();
