Linking to entries in Bard fields is very slow - ways to improve?

[321zeno]

Just checking if there is a way to improve the performance of looking up entries to link to in a bard field. At the moment we have around 800 entries spread across 6-7 collections. When selecting a bit of text, clicking on the link button, selecting Entry and clicking on the little directory icon, the lookup takes around 30-40 seconds to bring the entries panel up.

The URL that's called is {hostname}/cp/fieldtypes/relationship?config=eyJ0eXBlIjoiZW50cmllcyIsImNvbGxlY3Rpb25zIjpbInRvdXJzIiwibGFuZGluZ19wYWdlcyIsImJsb2ciLCJ0aWNrZXRzIiwiYXR0cmFjdGlvbnMiLCJ0b3VyX3BscHMiLCJpbmZvX3BhZ2VzIiwidGNfcG9saWNpZXMiLCJsdWdnYWdlX3BhZ2VzIiwiZ29fYmV5b25kX21hZ2F6aW5lIiwicHJpdmF0ZV90b3VycyJdLCJtYXhfaXRlbXMiOjF9&collections[0]=collection0&collections[1]=collection1&sort=title&order=asc&page=1&site=default&filters=e30=&columns=&search=

We are using the statamic/eloquent-driver package for storing entries.

We already looked into narrowing down the collections for linking in the bard field content but we do want to be able to link across all of them.

hmmm, wonder if a search index would help here? https://statamic.dev/search#connecting-indexes
