You generally see two different approaches to Virtual Machine Monitor design depending on the workload. The first is strict minimalism, seen in projects like Firecracker. Built specifically for running thousands of tiny, short-lived functions on a single server, it intentionally leaves out complex features like hot-plugging CPUs or passing through physical GPUs. The goal is simply the smallest possible attack surface and memory footprint.
For implementers, backpressure adds complexity without providing guarantees. The machinery to track queue sizes, compute desiredSize, and invoke pull() at the right times must all be implemented correctly. However, since these signals are advisory, all that work doesn't actually prevent the problems backpressure is supposed to solve.。关于这个话题，WPS官方版本下载提供了深入分析
