Thomas Gauvin shares computesdk's new runtime benchmark numbers: median latency dropped from 4.05s to 648ms and p99 from 6.7s to 1.1s.

The optimizations: scheduling the container on the same machine as its durable object when possible, preferring hosts with the image cached, and restoring a prepared VM instead of a full cold start.
