Terrible TTFB Times

RE: Terrible TTFB Times
Looks like the page is just about 100% cacheable (including the html) so the repeat views are done almost entirely from the local disk on the test machine.

Doesn't look like it is caused by database performance (at least from anything W3TC can see). Can you turn on the other debugging info?

It could be something in the Rackspace Cloud Sites dynamic scaling stuff but that would be pretty unfortunate.

It looks like you have Google Analytics on the site as well. You should go check the site speed report in your analytics dashboard (content->site speed->page timings->performance->server response time). That will give you a histogram of your server response times for the actual users visiting so you can see how it looks in the real world.

If W3TC's debug information can't provide any additional visibility I would recommend opening a ticked with Rackspace's support department to have them take a look. That's crazy-slow.
