max number of rules?

Does anyone know the number of audit rules that can be installed on a system before having to traverse the list of rules on every syscall starts to take a noticeable amount of time? I'm assuming no rules that generate excessive logs, so nothing like '-a exit,always -S execve' or '-a exit,always -S open'.
