My internet connection to the server is slowing down, maybe there is nothing wrong with the speed of the compiled program, i.e. the cpu or the hard disk.
I am accessing the server from CA of the USA.
As a comparison, I used the server on panel3 a long time ago, but lost my account due to a long period of inactivity. I reapplied for the server on panel6.
Maybe as priacc said, a lot of Chinese people are using the tunneling service. About this, I find it‘s maybe another interesting topic .😆
