Bug Description

Our batch size is small because our search and rendering codepaths are often inefficient, leading to timeouts on many different listing pages when we show more than 75 items.

Once we have fixed our default behaviour to be consistently fraction-of-a-second we should review our default batch size - using a data driven approach - to decide if a longer batch (and thus slower performance) is a better tradeoff for usability.

The batch size is predicated on performance. We will not raise the number unless someone also does the work to make the page faster.

I'm going to reopen this because longer listings would be nice; however its definitely long term and blocked on reaching a viable performance level.
