Well I guess you must have missed where I asked him if he would be happy if I changed +5 metrics to do whatever he wanted and he refused to answer me. That would easily fit within that scheme. Any percentage of nice value he chose. I suggest 50% of nice 0. Heck I can even increase it if he likes. All I asked for was an answer as to whether that would satisfy his criterion. > Ingo > > ps. please be nice to each other - both of you are long-time > scheduler contributors who did lots of cool stuff :-) I have been civil.
