As some may have seen in .NET 4.0, they've added a new namespace System.Threading.Tasks
which basically is what is means, a task. I've only been using it for a few days, from using ThreadPool.
Which one is more efficient and less resource consuming? (Or just better overall?)
The objective of the Tasks namespace is to provide a pluggable architecture to make multi-tasking applications easier to write and more flexible.
The implementation uses a TaskScheduler
object to control the handling of tasks. This has virtual methods that you can override to create your own task handling. Methods include for instance
protected virtual void QueueTask(Task task)
public virtual int MaximumConcurrencyLevel
There will be a tiny overhead to using the default implementation as there's a wrapper around the .NET threads implementation, but I'd not expect it to be huge.
There is a (draft) implementation of a custom TaskScheduler that implements multiple tasks on a single thread here.
