2.17.9. Standard Load Reduction Methods
Caching
You can enable browser caching of the site to reduce the number of requests to the server by instructions... V list of static files it is necessary to list the file extensions that should be cached, separated by commas. The recommended time for caching files is 1 week or more.
Note that caching is only possible for static content (images, HTML pages, font files). If the file extension is not specified in list of static files, caching rules for it can be set manually via a file .htaccess
your site.
PHP version
To improve performance, security and reduce the load caused by the work of PHP-scripts of the site, it is recommended change PHP version 7.0 or higher (the maximum with which the site scripts are compatible).
Attention!
Scripts written in earlier PHP versions may not be compatible with newer PHP versions. These scripts are recommended to be updated to ensure compatibility with the current version of PHP or replaced with alternative ones in terms of functionality. When using CMS, you should update the site core, installed themes and plugins to the latest versions.Optimization modules
To speed up the work of site scripts and reduce the load they create, you can use an additional service OPcache, designed to cache compiled PHP scripts bytecode in RAM. The technology does not require additional modifications, since it works directly with PHP itself.
It is also recommended to connect technologies Memcache(d)that implements in-memory caching of database queries, or Redis, depending on which one the site maintains or which one is most appropriate. Memcache (d) and Redis require site scripts to support these technologies.
When ordering the listed additional services for the first time, 7 days of test mode are provided. If you have one of the tariff plans businesshosting, then they are available for free within the allocated amount of RAM, so you can start setting up right away.
What won't help with load optimization?
Installing checkboxes in site optimization settings will not reduce the load on the server, it is to optimize the speed of rendering the page by the browser. If site scripts are not optimized, then enabling these options may increase the load on the server.
