Very interesting topic you have

I hope to learn something from this topic as I am total newbie to network matter.
may I know why is it so important on the speed of the 1ms ping test?
Is this for work or personal purposes?
Sharing the ip address not worry on people hacking?
What can we benefits with these speed test?
If I use vpn can I archieve the same result?
I'll try answer your questions;
Q: "may I know why is it so important on the speed of the 1ms ping test?"
A: 1ms or less(<1ms) is a typical response time for a wired connection in a LAN(local area network). If you see spikes in a LAN setting, it could mean there's bad configuration or a faulty/overloaded switch/router...etc.
Ping test is also used to show if devices can see each other in the LAN setting.
Q: "Is this for work or personal purposes?"
A: both:
Personal: As I used to play some competitive fps, ping stability is very important.
Work/Professional: This could show that the updates produced by windows 10 are causing stuttering or conflicts(I assume based on my findings).
Q: "What can we benefits with these speed test?"
A: I assume you mean speedtest.net. This is different from ping test. Speedtest to show roughly how much bandwidth you can achieve from a particular area/server.
Q: "If I use vpn can I archieve the same result?"
A: Definitely not, the speed will then be capped by the VPN server.
If you have 300mbps plan and you connect to a vpn server that has a cap of 100mbps, you are stuck with 100mbps.
If you have a 100mbps plan and you connect to a vpn server of 300mbps, you are still stuck with 100mbps.
hope this answers your questions
