That seems ridiculously low for page_fault1. > It's usually in the millions. per_process_ops = processes/nr_process since nr_process here is nr_cpu, so on the 2 sockets machine with 104 CPUs, processes are 8043568(base) and 8549112(head), which are in the millions as you correctly pointed out. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
