In a windows process is there any limit for the threads to be used at a time. If so what is the maximum number of threads that can be used per process?
722
Windows 10 limits max number (32) of threads with MMCSS priority, affecting Digital Audio Workstation software on multi-core CPUs.
Every process has at least one thread, but there is no maximum number of threads a process can use. For specialized tasks, the more threads you have, the better your computer's performance will be. With multiple threads, a single process can handle a variety of tasks simultaneously.
Each core can only run 1 thread at a time, i.e. hyperthreading is disabled. So, you can have a total maximum of 20 threads executing in parallel, one thread per CPU/core.
The maximum threads setting specifies the maximum number of simultaneous transactions that the Web Server can handle. The default value is greater of 128 or the number of processors in the system. Changes to this value can be used to throttle the server, minimizing latencies for the transactions that are performed.
There is no limit that I know of, but there are two practical limits:
dwStackSize in CreateThread or option /STACK in the linker command). If you use a 64-bits system this limit practically dissapears.
