Comment 5 for bug 1357402

I thought it might be useful to do some impact analysis as well. There is currently one community with over 1000 pages. That wiki would, obviously, benefit from doing something. There are 18 communities with over 100 and less than 1000 pages. That's not generally considered a huge number of objects, but object retrieval seems to be awfully expensive, so there may even be an impact at that level. There are 43 communities with over 30 and less than 100 pages. 354 communities have more than one page and less than 30. It might be useful to look at performance of the one large wiki after the tags portlet change hits, to see if we really have a performance problem worth fixing.
