Forums / Cotonti / Support / Tips for better performance with Siena ?

$cfg['cache'] and $cfg['cache_drv'] don't depend on content change frequency, they simply speed things up and are highly recommended. Your site might be 30-50% slower if you have cache disabled (btw, it's enabled by default in Genoa too).

Just these 3 are experimental and moreover they won't work properly on your site because they are not compatible with URLeditor plugin yet:

$cfg['cache_index'] = FALSE;
$cfg['cache_page'] = FALSE;
$cfg['cache_forums'] = FALSE;
