Author rebuilds part of Google's agent sandbox on Firecracker in ~2,200 lines of Go, measures snapshot restore
What happened
A Hacker News front-page post on November 8 describes an author who, after Google published its agent sandbox design, rebuilt part of it in about 2,200 lines of Go on Firecracker and benchmarked it. The work is not a full reconstruction of Google's sandbox, only an implementation and test of some of its design. On bare metal, snapshot restore took a p50 of 24.5 ms, 26 times faster than a cold start.
