Something that’s really got me annoyed in recent times is the ever increasing amount of bloat creeping into wordpress.
The last major feature to really annoy me was the inclusion of post revisioning by default with no obvious way to switch it off. Each and every time I altered and edited any posts a full copy was being kept in the database. I was beginning to wonder why my DB had grown 400% plus in a very short space of time.
To switch this off you need to add
define (‘WP_POST_REVISIONS’, 0);
to your wp-config.php file. Not exactly a user friendly method for the less technically minded of users is it? Surely this function should be switchable from the wordpress dashboard?
My second gripe is the sheer amount of RSS enteries held in the DB. Again there is no obvious way for the less technically minded user to disable these. Yes i know there are now plugins to do this sort of thing but yet again, should this not be a switchable option somewhere in the dashboard?
To do this at source add the following to your themes functions.php file.
define(’MAGPIE_CACHE_ON’, 0);
Place it with the other define statements in case you don’t know where exactly to put it.
