限制拉链速度

Question

I want to write c++ program that will put selected files from my lan into zip. But my problem is that i dont know how to limit speed of that process. Do you have any idea how to do that?

Sorry for my bad english :P .

Edit

Lets imagine lan with ~16 PCs and u want to "backup" 5 GB from each to server. And while this "backup" takes time u want to check something in web. Impossible because netwotk packed up.

What I want to accomplish is lowering load on lan by specifying speed in bytes. It doesnt even matter if it wont be exact, but precise has to be about 10-15%.

"You don't want to limit zipping speed, but lower bandwidth usage. – bartimar" Ure right.

Answer 1

The system will always try to execute orders as fast as possible. If you want to really slow down a process, you can make it

sleep()

It does not really make sense though to slow down your application. Are you maybe waiting for your data IO instead? In that case, use some sort of callback to compress data whenever enough is available.

如果您担心会对整个系统的性能产生负面影响，请将线程或进程的优先级设置为低于正常甚至空闲的优先级。
