ioctl is also quicker to do but it needs you to implement a character driver + a user space utility to issue ioctl command to kernel. Relatively I find it much faster with procfs.
Gustavo: Well I have not tried much with process as such, you can dig into its address space mapping and print information about its various memory areas (type of mapping), you can access its stack, heap, page tables, ofcourse you need to learn some memory management concepts too.
