 * Hi,
 * in reports from gtmetrix I see that this .js -> [https://mydomain.com/wp-content/cache/autoptimize/js/autoptimize_8976c970e86e3e2710c47c442c72debb.js](https://mydomain.com/wp-content/cache/autoptimize/js/autoptimize_8976c970e86e3e2710c47c442c72debb.js)
   
   it loads quite slowly. Blocking time is 230.6ms and total loading time is 381.4ms
   How can i reduce loading time?

 * the blocking time is because the JS is loaded with lower priority (as it is deferred).
   having less other resources loaded should help improving blocking time. transmission
   time is mainly dependant on file size, its 222KB compressed (with brotli), so
   probably well over 1MB of data. using less (plugins that use a lot of) JavaScript
   will help there.
 * hope this clarifies,
    frank

 * autoptimize_8976c970e86e3e2710c47c442c72debb.js is 821KB
    Will it give result
   if i compress it? And which program do you recommend for compressing of .js?
