1/27    If I run a CPU intensive job with "nice", how much responce time
        will I suffer, on a Linux box?
        \_ 40 angtrom-meters. why don't you just try it? there are a lot of
           factors. --aaron
        \_ Depends on how much you nice it, doesn't it?
           \_ The Linux scheduler is worse for this than something like the
              lottery scheduler that runs on soda.  But a CPU-bound job that
              doesn't do complicated I/O may not be hurt too much by being
              niced.  It all _does_ depend on your hardware, what other
              jobs are running, how much you nice it...
        \_ response.
                \_ I have a related question. What scheduling algorithm
                   does Linux use? Is it similar to round-robin with
                   multi-level feedback?
