Show Overview and Memory Usage on WordPress Dashboard, Memory Load on Footer Admin Control Panel with less mem consumption! Full 3.1+ compatible.
Preliminary note: this review applies to versions 2011.0723.2011 and 2014.0131-BUGFIX.0633-DEVELOPMENTAL.
Very good and useful plugin.
But won't run on PHP 5.5.0 and upper due to the use of mysql instead of mysqli (or PDO) in the code. 3 stars because the standard nowadays is PHP 5.5.x or PHP 5.6.x (PHP versions with active support).
