Super much overkill, we'd only need 125 MB/s for Gigabit connection and this is 3840 MB/s.
|
|
Also max request time is super nice + no errors.

Realistically this is the max over Gigabit connection.

Wow, this is 60 request per second compared to Hetzner's 47000, just wow! Repeated tests with hot cache resulted in a bit better performance, but still not Gigabit.

Abandoned the idea of using BuyVM, even though their unlimited bandwidth is quite unique in this price range in USA.
