Best of for speed up site and best support

i used lots of top of the line and popular plugins even paid (borrowed from friend) plugin to speed up my site score in google speed test… ALL failed to compete this one.

i mixed this plugin with Async. absolutely perfect.

during the test period, I face a site crash with this plugin that was an internal setting issue, and support was also superb. VERY fast reply from the author and fixed my issues with no time. now everything is doing very well.

i am using this plugin on woocommerce powered site.
