Hi Shashawat,

Here what to do if your website is suddenly slow after an update.

1. Check 404 errors-Use Insect tool and inspect the website.
2. Plugins-Make sure that your plugins are up to date. Make a backup of your site and start deactivating all the plugins and see if its improved site speed. Clear plugin cache because plugin cache can slow the speed.
3. Themes-Make sure to update the theme to its latest version.
4. Check for PHP Errors-If you are not familiar with PHP contact a developer to turn on PHP errors or contact your web host.

Try these hacks and make your website faster.

Thanks

It is as usual that website may runs slow after a wordpress update. The reason behind the slow loading of website after a wordpress update are -

• poor quality hosting
• No caching in place.
• No content delivery network to reduce loan on the hosting.
• no image compression or optimization has been done.
• old version of HTML.
• The version of PHP becomes old.
• you have slow or out of date plugins.

You should find the solutions for these too.
