工作学习 / IT技术讨论 / 刚运行了一个报表程序，照现在的速度要运行24小时才完成，unix下面有没有让这个进程占用更多资源或者提高优先级别？反正看机器还是75%空着，谢谢！！！！！！！

谢谢，我执行了renice -n -15 -p pid，好像作用不大，速度跟原来差不多，能不能把nice value降低到0？危险不？

我的理解是：这种冬冬只有在CPU很忙的时候才有用。CPU本来就很闲着。说明CPU该给process的时间都给了.还是改进算法帮助更大一点

事实证明了你说的，程序还是不急不慢地做着，谢谢

Because your program have lots of IO operation, the CPU is idle for most of the time. sigh. Some so-callled OS expert!

“说明CPU该给process的时间都给了“。如果你的中文的确非常差劲，你可以在谈天说地里发个帖子，问问有没有CSL班。

Hey. I am wondering if that is caused by priority inversion. Your Chinese version explanation is ok or not.

Another possible cause of your phenomena is "priority inversion". But that is rare.

你先把"rea-time"是什么搞清楚了在发言也不迟。

In real time operating system, priority inversion is a big problem.

Could you tell me where are you working? Send a PM to me. You are not busy at this time of the day at all. I like your job.

It looks that you have 4 cpus. only one cpu is full load. so 25% busy, 75% idle. if u can only use one process. u can speed it up.if the business logic allow u split input to 4 part, and run 4 process parallel, u can make the box 100% busy.

typo mistake "It looks that you have 4 cpus. only one cpu is full load. so 25% busy, 75% idle. if u can only use one process. u can NOT speed it up." can -> can't

i am not sure if u can use command 'top'. with it, you can have a view which program is busy and running on which cpu......
