I’m getting 0.10 to 0.20 second for page creation. Only using w3tc for page caching (APC) and minify (APC). Not using it for database caching.
I’m using Version 0.8.5.2
Works great for me also. One thing I found is that if you are using wildcard subdomains, when you type in a url without a site configured at that address it sends the site into a redirect loop.
To fix this I added:
define('NOBLOGREDIRECT', 'http://example.com');
to my wp-config.php
