> Listing comments in the admin UI seems useless due to terribly slow query in
> a Roller instance which has over ten thousands comments. Originally reported

> I think many unnecessary joins happen in it, So I believe it can be optimized
> a way without altering any of existing roller tables (I guess using {{NEW}}
> clause in the JPQL might help...).
> Anyway I wish I could see the result of {{EXPLAIN}} for the query...
