Can MODX Revo handle 40.000 users??

I’m wondering if MODx can handle 40.000 registered users.

Will it slow down the database or site performance when this user group is queried?

Will connecting to a secondary specific user database be a better option?

modxcms.com runs on tens of thousands of (restricted) users.

That said, the only slowdown you’ll see is on the Access Controls -> User Groups tree, if you open up the node for that user group. That said, you don’t have to open up that node at all - just edit the group itself. The rest of the data is in paged grids, which are scalable.

That’s good news! I will start working on this then.

The plan is to have this accessible on the front-end via "peoples" (found out about that one today).

People need to be able to query this user database on the front-end, can I use simple search for this or should I use something custom made?
Can I query for all the userfields or a standard set?

Thanks!!

Go custom, or file a feature request for a search option in Peoples.

All.
