IOCP scalability across hundreds of CPUs RRS feed

  • Question

  • I've tried to lookup and benchmarks featuring how good IOCP scales across hundreds of CPUs and did not find any.

    Will the interface be able to reach 10 mil+ IOPS on a top-end multicore hardware with proper scaling using thread pool with a number of threads optimized for a number of CPU cores doing all ops async way, with states decoupled from threads and no shared resources, i.e. for something simple like echo server?

    Since IOCP queue is itself a shared resource between multiple threads which all connections access, at some point the contention level of IOCP queue should affect the whole IOCP scalability. Any data on this?
