CB User List

Here is the scenario.

When my moderator edits another registered user profile, auto action captures the moderator's user ID and store it on this field called "cb_spid" in _comprofiler.

I created a list with the following filter (bel9ow) to generate a list for the moderator of the users which he edited.

when a user click on this list, it takes a long time to load. Is there a more efficient way to do this?

it is even worse when the user is no longer logged in after session lifetime. And that time userdata field="user_id" user="#me" is blank, and if he submits. It will do a query submit of a blank user_id am i right.

Depends on how many users you have. Substitution should actually improve performance as you're cutting down the userlist. Filters simply add to the WHERE statement of the query. There's really no improving it further if you've a lot of users beyond adding custom indexes to the table.
