I installed it after a lot of people praised it since the built in WP caching system was... not working very well. I noticed immediately it was more speedy. a lot more speedy. however there's one completely unacceptable bug: the first time a page is queried, if there isn't a cached version, it serves up a blank page. if I refresh it the full page is there. I emailed the author and recieved no response. anyone had this problem or have any possible solutions?
found a solution, for anyone curious: http://www.bloggingblog.net/wp-cache-and-the-blank-page-problem/
