#wordpress #wordpressdeveloper #performance #perfomancetesting

If you are a WordPress developer, you must have gone through these common problems after delivering the work to your client.

Client Response:

1. My site crashed when I installed the plugin or theme.
2. My site slows down after installing your plugin or theme.
3. Some JS events are not working.
4. Database queries take too long to process.
5. Ajax requests are not working or take too long to process.
6. And some more similar issues, etc.

So what procedure do you follow to measure the plugin or theme performance after the development process?

It is imperative to make your code clean, healthy, and secure because your code will be run by different types of users with varying configurations of servers and platforms.

The Solution

Here are some ways to measure the performance of your plugin or theme:

1. Always enable?Debug Mode, but some errors don't appear on the browser window, like Ajax errors or the program that runs in the background, so make sure you have enabled?Debug Log?as well so you can view them in the log file.
2. Open Browser console for JS errors.
3. Always use WordPress sniffer to check security issues in your code.
4. Install?Query Monitor?plugin to display JS, Php, and Database query errors. This will even show the queries that are slowing down your system.
5. Use?TasteWP?to create a virtual staging site and test your code or plugin on different WordPress & Php versions.
6. Use?Browser Stack?to test on cross devices (Android, ios), browsers, and software (Chrome, Safari).
7. Make a?Smoke Test?on your WordPress plugin.

I hope this guide will help you actively resolve problems, issues, and other hiccups about theme and plugin performance testing.
