I dont know if this is the right section but I just wanted to share this with you all.

My Oxwall site is on shared hosting on Arvixe and it was loading really slow... load time was up to 15 secs.

I read a few threads and noticed mentions to ensure debug and dev mode were false in config.php and when I checked they were... however after checking config file even further I noticed ther file was as follows:

define('OW_USE_CLOUDFILES', false);
    define('OW_DEBUG_MODE', true);    define('OW_DEV_MODE', true);
if ( defined('OW_CRON') ){    define('OW_DEBUG_MODE', false);    define('OW_DEV_MODE', false);    define('OW_PROFILER_ENABLE', false);}else{    /**    * Make changes in this block if you want to enable DEV mode and DEBUG mode    */
    define('OW_DEBUG_MODE', false);    define('OW_DEV_MODE', false);    define('OW_PROFILER_ENABLE', false);}

instead of:

define('OW_USE_CLOUDFILES', false);
if ( defined('OW_CRON') ){     define('OW_DEBUG_MODE', false);    define('OW_DEV_MODE', false);    define('OW_PROFILER_ENABLE', false);} else {     /**    * Make changes in this block if you want to enable DEV mode and DEBUG mode    */        define('OW_DEBUG_MODE', false);    define('OW_DEV_MODE', false);    define('OW_PROFILER_ENABLE', false); }

I changed it and site started running smoothly again!

I dont know what caused that in the config file but im just posting it here incase it helps somebody else at some point
