there are brace computer regularity questions.
Assume the brace regularity IDs listed here keep a prevalent niceness applift of 0. What is evil-doing with the subjoined order? renice -n 10 12345 23456 O You can solely renice single regularity, this tries to renice brace regularityes O You cannot lift their niceness appraises, solely inferior them Since the order is changing brace regularityes, you insufficiency to subjoin-p precedently the PIDs All of these are problems Nsingle of the aloft, this order has no problem
Counterpart 1: Since the order is changing brace regularityes, you insufficiency to subjoin -p precedently the PIDs
renice -n 10 12345 23456
‘renice’ charge is used to substitute scheduling priorty of single or more prevalent regularityes.
’10’ is the strove control. Scheduling control resides withing rove of -20 to +19
Since brace regularity IDs are to be reniced simultaneously so -p has to be used precedently each of the PIDs brace denote there are brace PIDs whose scheduling priorities are to be substituteed.
Counterpart 2: The CPU is spending 3.9%sy of its interval on wood regularityes
‘sy’ denotes wood space
In apex, CPU utilization can be spiritless down as subjoined :
