What you really want to watch out for with CakePHP ACLs is granularity. Make sure you aren't storing users in the aro tree if you don't need per user permissions. If your site is intended to have more than a few dozen users I highly recommend groupwise permissions only. Whether that improves performance or not isn't important. You will avoid allot of maintenance problems down the road. Looking after the permissions tree for thousands/millions of users is potentially a major undertaking. Once it gets large it is not an easy structure to debug or repair. You may fine yourself facing bizarre problems that are best solved by rebuilding the entire tree.

I was running up against the JOIN_LIMIT set by my host and getting the "Warning (512): DbAcl::check() - Failed ARO/ACO node lookup in permissions check. Node references: Aro: Array" error. This fixed the issue. Appreciate it. Thanks a bunch.

After having some troubles, I added this index on the ACO table : ALTER TABLE `acos` ADD INDEX ( `foreign_key` , `lft` ) It helps the many selects that have to be done to find the parent node when inserting large number of related objects. Thanks for the tip.

I was doing some research about possible cakePHP performance issues and found some post concerning slowness with cakePHP ACL's. Now this seems to be the solution. Great tip.
