Hi, so I'm having a bit of trouble getting a respectable score on pagespeed insights, and I wanted to know if anyone could give me some recommendations on what to include in my pagespeed.conf. My site is flashfed.com and I'm currently using the .09 beta with redis nginx and opcode cache. My main issue seems to be getting my images properly compressed, but it seems like there's a few large images that refuse to compress. Should I enable pagespeed caching? I'm not sure; I've only used pagespeed with the memcached option. Any other advice regarding optimization is welcome. Thanks.
