I have a google compute engine instance in us-central1-b running Centos 7 with 1vCPU and 3.75GB RAM.
According to the section "Egress throughput caps" on https://cloud.google.com/compute/docs/networks-and-firewalls my internet speed should be something somewhat close to 2Gb ("Each core is subject to a 2 Gbits/second (Gbps) cap for peak performance.").
I have installed speedtest-cli (pip install speedtest-cli) and performed many tests at different times of day. My max download has been 500Mb and max upload has been 72Mb.
I don't really expect to get 2Gb on this little VM, but I would expect it to be much closer to 1Gbps and a more synchronous connection.
Have I missed some documentation somewhere explaining the WAN speeds better? Am I not understanding the referenced documentation correctly? Is my system somehow misconfigured causing these really slow asynchronous speeds?
Thanks for any feedback.
Also, there is no other traffic on this system; it's just a test box.
