You also need "stat", for example: 18.Work:Terminus/Downloads> stat Task statistics:100.87% Task name ID NICE CPUusage Busy Activity ------------------------------------------------------------------- Enterprise 1 0 0.00% 0.00% 0.00% Voyager 2 0 0.00% 0.00% 0.00% ProcessManagerPPC 101 0 0.00% 0.00% 0.00% ramlib_PPC 102 0 0.00% 0.00% 0.00% ppcemu TimerObjSrv 103 0 0.00% 0.00% 0.00% Workbench_PPC10 104 0 0.00% 0.00% 0.00% rc5des_PPC_PPC13 105 0 99.10% 100.00% 100.00% Shell Process_PPC18 106 0 0.83% 0.87% 0.84% CPU load: 99.93% System load: 100.87% 18.Work:Terminus/Downloads> niceppc id 105 20 NICE value of task 'rc5des_PPC_PPC13' (ID=105) is set to 20 18.Work:Terminus/Downloads> Myzar is currently unable to set niceness under WOS, since priority-related tags of ppc.library/ChangePPCTaskAttrs() are not yet emulated in WOS ppc.library. I don't recall any performance loss by setting PPC client's niceness under WOS to 20, which is the best value since the client doesn't interfer with other PPC tasks.
