The project on wp + wc, there is also a wpml plugin. The google speed page metric (there will be a check on it) showed the results of 13/37 (mobile and desktop, respectively) + there is also a page (homepage) in German, which gives 9/27 !!! (there is a slider without which it is impossible).
.htaccess prescribed mod_deflate b modules all the rest as it should be, it slightly improved the situation by a couple of units.
I put all sorts of plugins for optimization, compression (Autoptimize, super cache ...), but the situation only slightly discharged W3 total cache. Now 22/54 and German on our 34/72! but you need 80+ everywhere .... What thoughts do you have about this?
