Is it 1 Mb of stack per thread? Or is that just CLR threads?
I want to know the memory over head of native windows threads (c++) and CLR threads as view via Task Manager.
Thanks

Essentially, the overhead is like the serial portion in Amdahl's law. So if the overhead is 1000 ns and the work, single threaded is 3000 ns, you use a serial fraction of 0.25. Really, the overhead is not serial, but rather parallel but proportional to the number of threads but that works out to almost the same thing.
On Windows machines, there's no limit specified for threads. Thus, we can create as many threads as we want, until our system runs out of available system memory.
We talked about the two types of memory available to a process or a thread, the stack and the heap. It is important to distinguish between these two types of process memory because each thread will have its own stack, but all the threads in a process will share the heap.
A thread is the basic unit to which the operating system allocates processor time. A thread can execute any part of the process code, including parts currently being executed by another thread. A job object allows groups of processes to be managed as a unit.
The default is 1 MB for both native and CLR threads. You can alter it, though that's usually a bad idea.
