I actually benchmarked this and wrote an article several years back, still very much applicable: https://jan.rychter.com/enblog/cloud-server-cpu-performance-...

Did you "preheat" during those tests? It is very common for cloud instances to have "burstable" vCPUs. That is - after boot (or long idle), you get decent performance for first few minutes, then performance gradually tanks to a mere fraction of the initial burst.

The article is worth the read.

I also did a benchmark between cloud providers recently and compared performance for price

That isn't the same as parent through, you are comparing VMs instead of dedicated servers
