Hi!
I've noticed, that Tomcat got much slower during startup. When using a Version 
> 7.0.27 (+ Oracle JDK 7), it takes much longer.

After this Step, with a newer version, it can take several minutes, until it 
continues.
During this "pause", I can see, that the disk i/o is pretty high.
When I switch back to an older version < 7.0.27, this goes much faster. It just 
takes seconds.

I am using a stock default config, only added "URIEncoding="UTF-8"". Tested 
with Windows 7 Professional and Ubuntu 12.04.

I don't know where to start for debugging this problem. Any Ideas?

Is this a large webapp with many classes? I think around 7.0.29 something changed with annotation scanning. There was much discussion about memory issues through some changed behaviour as well. Maybe you could try to check with metadata-complete from https://tomcat.apache.org/migration-7.html#Annotation_scanning


Bye,
