By default each domain will get a fair share of the CPU on which it runs -- if N domains are all CPU-bound then each will get 1/N of the CPU. Domains which are woken by an incoming event (eg. network packet or key press) should get run with reasonably low latency. By bogged down, do you mean that interactive response suffers? What is the busy domain doing -- just CPU-intensive work and no I/O? -- Keir ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
