Greetings,
I've made a minor logging change that makes the logs far more useful.
In rcmail.php:shutdown, change this:
$log = $this->task . ($this->action ? '/'.$this->action : '') . (isset($mem) ? " [$mem]" : '');
to
$log = self::$instance->get_user_name() . ':' . $this->task . ($this->action ? '/'.$this->action : '') . (isset($mem) ? " [$mem]" : '');
which makes tracking down performance issues much easier.
