Which cache plugins do you recommend for use with Blocksy?

Hi,

Blocksy theme is already pretty fast as is, but can you recommend some cache plugins that will work well with Blocksy? Have you done any testing to see which cache plugin has best performance with Blocksy? We’ve tried WP Optimize and WP Fastest cache and seen some improvements. When using WP Optimize we notices that images stopped appearing when the minify options were enabled.

Please share your thoughts and recommendations on best cache plugins to use.

Thanks!
