@frederick, I am running into the same issue opjacht is experiencing with WooCommerece and TTFB. Do you have any suggestions on what can be done to speed things up till the matching logic is incorporated in W3 Total Cache?
Also, is there an ETA for the feature?
My site is http://www.alohayall.co - I am a huge fan of your work, W3 Total Cache is my favorite plugin and, by far, the most important component in each of my sites!
