Optimizing a store [PrestaShop 1.6, 1.7, 8.x]

Your shop is slow?

It's time to optimize

What is optimization?

1) installation of modules from different sources is associated with a mass of errors. Theoretically, however, the errors do not slow down the display of the store.
2) during optimization we check what modules generate errors, warnings and remove them
3) Some of the modules do not use the standard cache generation scheme - if it is possible to add a cache
4) Database optimization for the amount of unnecessary queries by eliminating them to a minimum for the most popular sites
