But those same things (and more), in the majority case of completely benign workloads, are significantly better for resource utilization and performance. I don't think their model is "run everything in V8 isolates as the only isolation primitive", I believe it's closer to "run things with V8 isolates as the floor, dynamically trading efficiency for security in response to runtime (and I'd also assume static) analysis". They also add restrictions to make it more difficult/expensive for code to exploit side-channels (ex. changing the resolution and behavior of `performance.now ` and `Date.now`…
