Hi, 2012/1/6 Adrian Knoth <adi@xxxxxxxxxxxxxxxxxxxxx>: > I was wondering why pthread_create() should cause minor page faults when > there is a pre-allocated pre-faulted 100MB memory pool. That pre-allocated block of memory is used by Glibc for its malloc routines. While doing a pthread_create() you go to the kernel. Inside the kernel many functions allocate memory as well. This is outside the control of the C-library. Probably some function inside the kernel allocates this memory and uses it, resulting in these page-faults. One example is allocating memory for the stack.
