Hi I have a Joomla 3.10.10 website running on Siteground.
We have good performance when measure in Google Page speed insights for PC performance (score= 97) but it is running slowly comparatively for mobile (score=60).
Some things don't seem right, for example when I use CURL command to look at the headers and I get;
The thing that looks wrong is (there may be others to a trained eye like yourself) that there is a X_Proxy_Cache : MISS
We have activated MEMCACHE and other Siteground cache and speed performance features. I have also installed and switched on features in JCHOptimize. the template also has performance improving features that I use.
It may be there is a something we forgot to do or that there is a conflict with the different cache/perforance tuning options.
We would like a Google PageSpeed insight score of around 90 for SEO purposes.
It may be an easy fix for someone that knows there way around Joomla and/or Siteground.
The site should obviously be working correctly after it has been tuned.
