Ten top tips to optimising WordPress.
1. Use a Content Delivery Network
See: CloudFlare
2. Enable Gzip on your server
Tool to test if your WordPress server is Gzip enabled: checkgzipcompression.com
# compress text, html, javascript, css, xml: AddOutputFilterByType DEFLATE text/plain AddOutputFilterByType DEFLATE text/html AddOutputFilterByType DEFLATE text/xml AddOutputFilterByType DEFLATE text/css AddOutputFilterByType DEFLATE application/xml AddOutputFilterByType DEFLATE application/xhtml+xml AddOutputFilterByType DEFLATE application/rss+xml AddOutputFilterByType DEFLATE application/javascript AddOutputFilterByType DEFLATE application/x-javascript AddType x-font/otf .otf AddType x-font/ttf .ttf AddType x-font/eot .eot AddType x-font/woff .woff AddType image/x-icon .ico AddType image/png .png
3. Identify slow plugins
4. Compress images
5. Expiry date & caching
Google’s PageSpeed Insights reveal some interesting facts how WordPress performance can be improved, one of which is to use Compress (see #2) and to set the expiry date of static files.
# associate .js with “text/javascript” type (if not present in mime.conf) AddType text/javascript .js # configure mod_expires # URL: http://httpd.apache.org/docs/2.2/mod/mod_expires.html ExpiresActive On ExpiresDefault “access plus 1 seconds” ExpiresByType image/x-icon “access plus 2692000 seconds” ExpiresByType image/jpeg “access plus 2692000 seconds” ExpiresByType image/png “access plus 2692000 seconds” ExpiresByType image/gif “access plus 2692000 seconds” ExpiresByType application/x-shockwave-flash “access plus 2692000 seconds” ExpiresByType text/css “access plus 2692000 seconds” ExpiresByType text/javascript “access plus 2692000 seconds” ExpiresByType application/x-javascript “access plus 2692000 seconds” ExpiresByType text/html “access plus 600 seconds” ExpiresByType application/xhtml+xml “access plus 600 seconds” # configure mod_headers # URL: http://httpd.apache.org/docs/2.2/mod/mod_headers.html Header set Cache-Control “max-age=2692000, public” Header set Cache-Control “max-age=600, private, must-revalidate” Header unset ETag Header unset Last-Modified
