Slow website
How to find out why your site loads slowly and what you can optimise before opening a ticket.
A slow site can be caused by the site itself, the database, too many requests or plan limits. First find where the bottleneck is.
Symptoms#
Long loading times, especially in the admin area, timeouts or occasional slow responses at certain times of day.
Causes#
- large images and uncompressed resources,
- too many plugins or a heavy theme,
- an outdated PHP version or disabled caching,
- slow database queries and a bloated database,
- external scripts (ads, widgets, fonts) that slow loading,
- reached resource limits of the plan,
- bots or attacks generating traffic.
What to do#
- Measure speed with a testing tool (e.g. PageSpeed Insights or the browser tools F12 → Network) and see what takes the longest.
- Check the PHP version and move to a newer supported one if the application allows (Changing the PHP version).
- Turn on caching and compress images. For WordPress: Speeding up WordPress.
- Remove unnecessary plugins and old files.
- Check usage of space and inodes (Space and inodes).
- Look at the statistics in cPanel (Metrics → Visitors/Raw Access) for an unusually large number of requests from one address.
Ticket#
Open a ticket with the domain, the slow addresses, the time of occurrence, the speed test result and a list of recent changes.
