[seam-dev] JNDI Lookups, and UserTransation lookup breakdown

[Jay Balunas]

The seam-gen test went about the same.  I used the same seam-gen application
and setup that we use for release testing - see:
http://fisheye.jboss.org/browse/Seam/trunk/release-process.txt?r=8379#l274for
the table schema, and information.

741 ms - 1,214 inv. [NAME] java:comp/UserTransaction
20 ms - 1 inv. [NAME] java:comp/env/security/securityMgr
2 ms - 15 inv. [NAME] java:/perfGenEar01EntityManagerFactory

This was about 15 pages with a mix of table navigation, and login/logout,
etc...
