Do you usually use vagrant for magento? Our live sites are very fast but only because of varnish. We reach under 1 sec load time. However on vagrant it takes ~30 seconds for a page load. With Mamp it takes ~10 seconds.
I've checked the settings, there is no difference between mamp and vagrant instances. Having varnish in developing mode quite pointless, so how do people manage to use vagrant with magento?
