If I do a taxon variant search on "Metepeira*" I get 7 items. If I then click on the "Tree" tab, it takes 1 minute and 20 seconds to get a list of trees. That strikes me as quite slow for a join with only 7 taxa. I tried searching on "Mara*" and got a significantly longer list, then clicking on the Tree tab took a very long time (I gave up after six minutes). Ideally this join should be better optimized.
