I'm using the defaults, since I haven't actually got a workload besides compiling kernels ;-) Changing these values is very much workload dependent, the PRIO should be high enough not to cause memory starvation, but low enough not to disrupt anything important, and thus completely dependent on you favourite RT workload. The same goes for the DELAY, too long and you run out of memory, too short and you get more overhead, depends on your workload, your machine memory size etc.. Paul should of course be put on trial for giving us these knobs, but seeing where they come from I totally understand they exist ;-) -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
