a code like below will start a new thread to do the job. Is there any way I can control the priority of that thread? Task.Factory.StartNew(() => { // everything here will be executed in a new thread. // I want to set the priority of this thread to BelowNormal }); This is one of "not to do" when you decide whether to use thread pool or not ;-) More details here: http://msdn.microsoft.com/en-us/library/0ka9477y.aspx So the answer is "No, you cannot specify particular priority for thread created in Theads Pool" As of general threadings I bet you already know about Thread.Priority property As

TPL TaskFactory.FromAsync vs Tasks with blocking methods

由 徘徊边缘 提交于 2019-11-26 15:47:25
问题 I was wondering if there were any performance implications between using TPL TaskFactory.FromAsync and using TaskFactory.StartNew on blocking versions of the methods. I'm writing a TCP server that will support no more than 100 concurrent connections. After writing code with the first option & chaining multiple read & write operations with continue with, I was left with ugly, hard to debug code. I believe writing code with the synchronous version & then wrapping it with a Task would decrease
