All test results are in seconds.  The first three columns of tests are done using Magento 2.3.2 + Codazon Fastest - Ellyana theme - Most features disabled.  The fourth column is done on Magento 2.3.2 _ Luma theme.  The tests were aimed to show if Magento is faster on NGINX + Varnish + Redis configuration.  The results are mixed - you can see the table bellow.

It looks like in some cases NGINX + Varnish + Redis configuration is actually faster.  However, the Magento Theme  Codazon Fastest - Ellyana theme is not so fast as the name would suggest.  We installed the same configuration on a local server running an old Pentium i5, 8 GB ram running on Ubuntu and Magento was much faster than any hosting / cloud hosting provider we had tried before that.
