任务并行库占用生产服务器上的大量空间

Question

I am using –

Task task = new Task(delegate { GetRecordsForEmailReplies(headingList, partialEntity); });
task.Start();

to run some heavy methods, but the problem is it's consuming lots of space of CPU on server some time IIS Work process increased above 60% thats why server gets stuck.

Is there any solution to manage this problem, so please let me know? or any other option to run these heavy method without blocking the page load?

Answer 1

The suggested means for creating a new Task or Task<T> is to use Task.Factory.StartNew with .NET 4.0 or Task.Run with .NET 4.5 . There is a detailed explanation from Stephen Toub here on the topic.

He explains that it's more efficient:

For example, we take a lot of care within TPL to make sure that when accessing tasks from multiple threads concurrently, the "right" thing happens. A Task is only ever executed once, and that means we need to ensure that multiple calls to a task's Start method from multiple threads concurrently will only result in the task being scheduled once.

Again, use the Task.Run instead:

Task.Run(() => GetRecordsForEmailReplies(headingList, partialEntity));
