Well it should be faster if you're replacing the VM layer and running docker on top of bare metal kernels, in theory you could use a cheap dedicated hosting provider to host a K8S cluster and probably outperform a managed cloud offering price and performance wise - but in practice this shit is so unreliable I would never want to be the guy on call maintaining this - they would need to pay me a lot more than the delta between managed cluster and bare metal. For non-critical computationally expensive stuff like analytics and BI it could make sense.
