[Plugin: W3 Total Cache] pgcache is always empty

Hi

I have set up the plugin and all the settings i think i should have set. I installed the sitemap plugin and configured the precache settings. But when i look in pgache it is always empty.

Is page caching on? The site seems quite slow still ~ 3 second page load
