> the “warmup” time for a unikernel is subsecond whereas the warmup time for, say, containers is… let’s just call it longer than the warmup time for the water i am heating to make some pourover coffee after i finish my silly post. to dismiss this as a profound advantage is to definitely sell the idea more than a little short.
I'm surprised to read that unikernels would start up much faster than containers. It seems like a unikernel needs to do more work (load kernel, and load app), in a more restricted way (hypervisor) than simply loading the app in a cgroup + namespace and letting it rip.
Are you sure this is an apples to apples comparison of similarly optimized images?
