You see wrong. And I meant MSSQL, of course. Fixed.

Can you than please give a technical reason for you to insist on waiting on more than 64 threads in a single API call, having simply too many threads for good performance anyway when IO Completion Ports could be used instead?

  • He probably doesn't have 64 threads, but he may have much more than 64 files or sockets. After all, the response was to the statement that "WaitForMultipleObjects as a kind of super-select to wait on anything". It clearly isn't, with this arbitrary limitation.

    The problem with Windows is that there isn't any such super-select, unlike on Linux (see epoll, signalfd, timerfd...). You should take a look at my SO answer which lists six different ways to use sockets in Windows: http://stackoverflow.com/questions/11830839/when-using-iocp-...

    • Whatever he has more, waitfor is not the optimal way on Windows for that so it's still a complaint that round holes on Win32 are poor fit for his cubes. First choosing tools then complaining that they don't fit to some goal is typical for beginners.
