The "VM-isolated sandbox" is apparently not referring to the JavaScript VM but to a hypervisor, according to the text a bit further down on the page. I wouldn't expect that to be particularly fast or efficient, especially not if you're already running in a VM and have to use nested virtualization (if it's even available).
replyits pretty fast tbh, though third-party benches would be great to have!
replyIs it essentially implementing a paravirtualized OS that runs the JS runtime? Presumably you have to allocate the memory for the VM up front, or how does that work?
replyon linux its kvm, on darwin its hypervisor.framework, the memory is not upfront, by default 256mb is lazy allocated, and ~35mb are used by both ant + the vm. the kernel is https://nanos.org with patches to get ant+networking running smoothly
replyDeno has that! Come join us :P no affiliation, just a happy user.
