Using a single condition variable for synchronization across all GL messages is very slow on Windows and uses up to 20% CPU usage in some workloads due to lock contention and false broadcasts. Using per-message event handles reduces the CPU usage to negligible amounts despite having to allocate a new event handle for each message. |
