Performance testing

Performance guide

Managed WP hosting

Note: this section contains hosting affiliate links.

  • The host is often the main determinant of performance
  • Use a host that’s optimized for WordPress
    • Speed
    • Security
    • Updates
    • Tools
  • SiteGround: fast, secure WordPress hosting
    • SiteGround is an excellent WordPress-optimized shared host. They’re fast, secure, and reliable, yet inexpensive. They’re the host I most frequently recommend to small business and nonprofit clients.  From firsthand experience, I’ve found their plans to be superior to similar hosting plans from GoDaddy, Bluehost, DreamHost, Hostmonster, HostGator, iPage, and small local hosting companies.
    • WordPress Hosting
  • For clients with larger and/or higher-traffic sites, or who need additional benefits, we recommend WP Engine, but for most smaller sites, SiteGround provides great features for relatively low cost.

Caching

  • Use managed WordPress hosting; they often handle caching. Even if you’re not using managed WordPress hosting, use the host’s caching as much as possible.
  • WP Super Cache: simpler, less problematic than W3 Total Cache
  • W3 Total Cache: more powerful but more problematic than WP Super Cache

Caching, queries, transients

Brian Richards

W3 Total Cache

  • Turn on all caches
  • Enable Page Cache
    • For e-commerce, don’t cache cart, checkout, my account pages

Custom queries

  • Queries are controlled by query.php in core
  • Queries use WP_Query class
  • Look at query.php and see all the filters available. You may not want to write a custom query; you may be able to modify the main query with pre_get_posts(). It’s more efficient to modify the main query that WordPress is already running than to add a new query. Be very specific about when you’re going to modify the main query; use conditionals.
