I have a question about a way I can measure download speed of my server in my case. Basically I have a dedicated server at Namecheap and I purchased the 1GBps port speed. (Not to advertize). But when I run speedtest-cli
I never get more than 300 Mbits/s. But I have seen forums were people reach ip to 900 Mbits/s. And the servers that speedtest-cli
are only 45 km away.
I talked to them about this and they said the best way to measure download speed was using iperf
. They got these results:
------------------------------------------------------------

But the fact is, when people download things they never open up several ports to do it. And how is it that my server is not matching with the rest on the same test. Something seems off. Can anyone tell me if the data their presenting proves my server is 1GBps? Or am I being cheated?
