This give me an extra advantage because I can sort the most important
servers first to grant a fast response to critical apps.
ACL evaluation results are stored in the idl cache, so the more a
given rule is exercised, the quicker the result sets to that rule
should be, if you have a good idl cache setting.
No they are not. Index lookups are cached by the IDL cache; that has
nothing to do with ACL evaluation.
Ah, sigh... Some confusion on my part there. ;)
I still think the modifications to the BDB cache are definitely worth
