Getting slowww results, Wordpress+W3TC

[RonSL]

I'm working on a friend's Wordpress site that uses W3TC and MaxCDN, trying to get it to run faster. I've been getting insanely slow results. In fact, disabling all the caching in W3TC makes the site faster, not slower.

Here are some results with W3TC enabled:

(with minify shut off)

Here's what I get when I shut W3TC off:

What they all have in common:
- Time to First Byte is high for suitelife.com
- WebPageTest does not detect the CDN weather it's on or not

I'd be the first to admit that I don't really know what I'm doing, but I've followed several sets of instructions of getting W3TC and MaxCDN working together, and I don't understand why I'm seeing no improvement (and in fact am seeing the opposite).

I'd appreciate any input.
