This Space is getting slow

Summary: This is probably the first Space that is big and complex enough to hit real efficiency problems in Querki. Time to start profiling and optimizing.

Note that only certain parts are slow. The front page is taking a very long time to render (several seconds), but individual Issues are still quite quick. So the problem doesn't seem to be general load. It is likely either the filtering/processing of the entire Space, or rendering many items at once. Do some serious profiling, to see where the problems really are.

Dealing with this is probably going to require export/import, so I can pull this Space down to my development machine and seriously dig in.
