the tests were for these local (metal direct connect ssds). The issue is not network overhead -- its that just like everything else in cloud the performance of 10 years ago was used as the baseline that carries over today with upcharges to buy back the gains.

there is a reason why vcpu performance is still locked to the typical core from 10 years ago when every core on a machine today in those data scenters is 3-5x or more speed basis. Its cause they can charge you for 5x the cores to get that gain.

That is transparently nonsense.

You can disprove that claim in 5 minutes, and it makes literally zero sense for offerings that aren't oversubscribed

No. In some cases I think AWS actually buys special processors that are clocked higher than the ones you can buy.

The parent claims that though aws uses better hardware, they bill in vcpus whose benchmarks are from a few years ago, so that they can sell more vcpu units per performant physical cpu. This does not contradict your claim that aws buys better hardware.

You are talking about real CPU not virtual cpu
