Perf - reusing same regex object in joinwalker objects
------------------------------------------------------

                 Key: NH-2774
                 URL: http://216.121.112.228/browse/NH-2774
             Project:  NHibernate
          Issue Type: Patch
          Components: Core
    Affects Versions: 3.2.0Beta2
            Reporter: Roger
            Priority: Minor
         Attachments: joinwalkerRegexPerf.patch, perfRegExStatic.PNG

When upgrading, my test suite took approx 17% longer to run (most of the overhead time spent when building session factory). This was caused when creating regex objects in joinwalker. Now reusing same instance instead, the overhead is gone.

Adding snippet from dotTrace as attachment.
