If you are a free user:

The speed of free servers is a bit slower than the premium servers.

X-VPN premium servers provide faster and more stable speed, you may take the free trial and try with them. 

If you are a  premium VIP:

The speed depends on both your local network and X-VPN VPN servers. 

1.Check your local network

2.Select different servers to connect

3.run a speed test to choose the fastest location for you.

Please tap/click "Select Location" to pull up the server list page, then click the clock icon to run a ping test. 

You can choose locations you want to test in the list.

It may take about 10 minutes to finish the test, please choose the first server with the highest download speed.

Notice：VPN can‘t substantially increase the speed of your local Internet, it may work on glocal connection. For example, when you browse the Japan website in the United States, connecting to the Japan servers may be faster.
