Issue MDL-39873: check usage of class_exists to avoid usage of autoloading
Currently class_exits is not passing second parameter as false, in blocklib.php and pluginlib.php, because of which autoloader is called and hence can hit performance with autoloader functionality. Look at other usage of class_exists function and pass second param as false, where appropriate. http://php.net/manual/en/function.class-exists.php
