Thanks, Mark. We found some information regarding performance issues in Tomcat 
7 but could not relate them to the problem we were seeing.

This has been raised as bug 51532 
(http://issues.apache.org/bugzilla/show_bug.cgi?id=51532).

That looks familiar.

Tomcat 7 re-factored the Jar scanning so that consistent code (that
fixed some edge case bugs) was used for annotation scanning, TLD
scanning etc as well as making the whole process extensible.

Along the way, a few places that used file URLs switched to JNDI urls
and in some cases that triggered a performance hit. Looks liek you have
found another one. Open a bugzilla issue and soemone should take a look
for the 7.0.20 release.
