A slow iPad may not actually be slow; a poor internet connection may be the cause of the performance issues. To troubleshoot these issues, test your iPad’s internet speed. Many apps rely on the web, and a poor connection can affect these apps in different ways.
How to Check Internet Speed on Your iPhone or iPad (iOS)
To test your iPad, download the Ookla Speedtest mobile app. To check the Wi-Fi speed on your iPad, launch the app, allow location services if prompted, and tap the Begin Test button.
The Ookla Speedtest screen looks like a speedometer on a car, and like that speedometer, it doesn’t have to hit the speed limit to register a fast connection. There’s nothing to worry about if it doesn’t hit the speed limit. It depends on how you use your iPad.
Test your connection more than once to get an idea of your average speed. It is possible for Wi-Fi to slow down for a few seconds and then speed up again. Perform multiple tests to account for any variations.
