@alexmeshkin There are multiple problems. Definitely the spread of the virus is the root cause. But also a system that responds to congestion by delaying results, degrading their utility. Congestion problems occur in all sorts of systems, usually a solution is building in back pressure.
@阿列克斯金：有很多问题。毫无疑问，病毒的传播是根本原因。但同时也是一个通过延迟结果来应对拥塞的系统，降低了它们的效用。拥塞问题发生在各种系统中，通常解决方案是建立在背压中。
