Awesome plugins and the respectable author

Both Autoptimize and Async JS plugins can extremely speed up my website. Before I move on to these tows, I have used another popular Cache plugin for a long time. with Autoptimize and ASync, I have never thought that my site would be able to be up to lee than 2s from more than 4s, even though I have to exclude some JS script manually. But it is worth it to do so. When I faced the issue of excluding script from js minification, I didn’t expect the error can be solved very fast even more because this is a free plugin, but Frank rapidly answered me just in few hours! And told me, all I need was to add a simple class of the JS, and then the magic happened. Thank you, Frank, and his great plugins. ??
