Evaluate Forums Performance from a "site with a large number of groups" perspective

Description

We have had reports that sites that utilize a large number of groups tend to slow down loading in forums. We should do a yourkit analysis of this scenario to see if there is anything we can do to improve this performance.

Site.getGroupsWithMember() costs most of time for Forums which is in the site have a lot of groups. just did the same thing which I needed. We will notice the big performance's improvement for Forums tool which have a lot of groups after is checked in to trunk.

I did a yourkit analysis for site SP08-BL-EDUC-W505-C7308. What I found is it costs most of time for UIPermissionsManagerImpl.initMemberShipForSite() which later related with Hibernate db access. Since super user doesn't call that method. So it is fast.

Ying, can you look into this? We've got a report of this locally

The local site is SP08-BL-EDUC-W505-C7308
And this is Derek's analysis . I went into this site as a super user(no group) and as a student in the course who is in a group. As a super user, response times were <1, as a student in a group, it was taking
3-5 seconds to move from page to page. I imported the forums to my test site and noticed the same behavior.
