Back in May 2018 I tested out a fresh install of WordPress on a Powweb shared hosting environment with the free “affinity” theme and ran a test on Pingdom (search limit reached after only three searches which is why I now use gtmetrix). Results were a load time of 1 second for the 1MB page size read faster than 85% of sites. But the performance grade was still a 65 D and some of the failures included the following: Leverage browser caching (grade: 3/100) | Specify a Vary: Accept-Encoding header (6/100) | Remove query strings from static resources (12/100).
The caching plugins recommended by GTMetrix are WP Fastest Cache and, if that doesn’t work, WP Super Cache.
