我最近比较了.NET中的OmniThreadLibrary和ThreadPool,我发现Omni在最大线程中受到更多限制 – 允许60 – 而.NET在.NET 4.0中可以达到32768.
为何如此限制？
解决方法
这是一个历史性的选择,曾经可能被解除.限制仅适用于线程池实现.
对the website给出了解释,说明如下：
The limitation of 60 concurrent threads only applies to the thread
pool. Thread pool is designed for fast execution of many small
requests,not as a storage for rarely-active threads.You can just skip thread pool and use OTL tasks directly. That way you
can create many hundreds of them.
这个限制的原因是深层内部[OtlTaskControl] TOmniTaskExecutor.WaitForEvent使用具有此限制的MsgWaitForMultipleObjectsEx.如果对具有超过60个并发运行线程的任务池实际需要,则可以规避此限制.
