Yeah, the problem is that in order to make all those columns sortable I had to do some complex queries (i.e. sub queries inside a SELECT statement). You brought this to my attention a while back Torgos, I just never got around to come up with a more efficient way to query for all this aggregate data. A quick fix would be to ditch sorting for certain columns. I'm still up in the air to do about this, I'd like to revisit this after I take care of a few other issues.
