Agree speedtest-cli is not perfect, but you can see from my test I got near the 1Gbps that DigitalOcean advertises. I am curious if AWS LightSail even breaks 100Mbps.
In terms of network speed not being important, that's not true. Lots of workloads are network bound not i/o bound (load balancers, web servers, etc).
That's what I meant. The results show that the DO box is fast enough, but a slow result doesn't indicate that you can't saturate traffic. It's really hard to test without real-world traffic, haven't found a reliable way to do so yet.
