The major reason for the initial excitement about containers was the relative efficiency as compared to VMs. I understand that Firecracker has a low memory overhead and a fast startup time but I'd be interested to know what the virtualization overhead is in terms of cpu performance. I poked around on google a bit for a few minutes but didn't find anything.
