Sufia 7.3 curation_concerns/base/show.html.erb

We’ve customized this page, but like the original, it lists all members (for the purpose of this profile all filesets), without pagination, with some metadata and hyperlink actions, along with some cancancan guards for some of them. I’m not sure if the original uncustomized would have exactly the same performance characteristics — it’s possible we’ve added more calls to metadata attributes and generation of hyperlinks than the original.

We have already implemented the Solr fetch n+1 workaround. Adapted from https://github.com/pulibrary/plum/blob/master/app/factories/efficient_member_presenter_factory.rb.

This profile is of a sample work with 200 file set members — with each page of a manuscript being a member, we do have works with 200-400+ members in our actual data. This profile was done with production-like config, and after a few requests were made to warm things up.

This profile is not of the whole action/render, but just wrapped around what I ident
