The most interesting part of this for me?<p>> We were able to achieve these improvements because the second generation execution environment is based on a micro VM. This means that unlike the first generation execution environment, which uses gVisor, a container running in the second generation execution environment has access to a full Linux kernel.<p>They moved to microVMs.<p>> Then we switched to the second-generation execution environment and it sped up our boot time by 4x!<p>And they were 4x faster to start-up than containers with gVisor were for at least this one customer.
