Show HN: Tarit – a hypervisor which is 2x faster than firecracker

  Where does the headline come from? The README metrics say there are no published benchmarks.

    Mostly from internal tests. And also some of the companies we know uses firecracker has published benchmarks[1] 1. https://x.com/mlejva/status/2069424250709307451?s=20 https://x.com/mlejva/status/2069424250709307451?s=20

  Not clear where 2x claim in the headline came from, I don’t see it in the linked site.

  Not "yet" with "virtio-balloon", so basically where firecracker was for quite some time. With that you can only grow, but not shrink memory if I understand correctly. So useful for "I'll run and terminate" but not for "I'll run next to others with varying runtime and memory usage". Will be interesting to see how https://github.com/rust-vmm/rust-vmm https://github.com/rust-vmm/rust-vmm is going to develop, sounds like something like that could have a lot of use-cases for privilege separation but also embedded testing frameworks.
