Performance

The following are some tips and tricks to improve performance of Rails Admin with larger databases.

Edit Page Performance

A common source of slow-loading edit pages for me is fields that are associations to large tables being editable.

For example, if I have a User model which has_many :comments, the comments field is editable (the default), and I have millions of rows in my comments table, then when I attempt to load the user edit page, Rails Admin appears to issue a select * from comments.

Marking associations to large tables as readonly has often been the culprit behind poor edit page performance for me.
