For some reason the template content isn't being cached. If you turn on vB debug mode, does vB optimise tell you it's fetched templates from cache, or that it needs to query them to cache?

If unsure where vB Optimise messages are, it's the bottom drop down menu on your pages after enabling debug mode, which can be done like so by adding this in config.php:

$config['Misc']['debug'] = 1;
