Hi all, On a "normal" kernel (no special tuning), kernel space tasks have more priority than userspace ones? Is that correct?
Here is what I am experiencing and trying to find a solution. I have an IXP425 based board, running madwifi for the Atheros cards, acting as a wifi router. I also use userspace programs (boa http server and cgi apps) to configure it. When the board is on heavy load (Wireless stations connected to the board and pass lots of traffic), my web apps run extremely slow. Even the serial console responds that slow. Is there a solution to this? Would CONFIG_PREEMPT help at all? Or for something like this you have to use a RT kernel? Assuming that the user space application can have a specific pid, is there any "patch" that can be applied to the kernel's scheduler to give it some more priority? I cannot tell if this slow down occurs to kernel versus user space priorities, or to the bunch of interrupts per second.
