empty From the high level, it is a MPMC queue. From the low level, it is a performant and balanced design with multiple SPSC queues. Key Tokio Scheduler Perf Gap: Synchronization is required for stealing Number of Producer Cores Throughput / Relative Value DLB Tokio Crossb eam Std DLB-Assist Scheduler Design • Each processor has own run queue • DLB does balance Next Step • Do benchmark for different

modifications. Threading • In NativeScript by default everything runs on the main thread. This design has both pro’s and cons • Pros: Easy access to anything dealing with GUI • Bad: Jank when doing

deprived of some of its most powerful conceptual tools • This lack not only impedes the process of design within one mind, it severely hinders communication among mindsPast Breakthroughs Solved Accidental

VI: Conclusion52 Takeaways • C++20 is super cool and has a ton of new stuff! • The design of the library presented some challenges for Windows, but we made it work! • Time is so much
