Alto Uso De Cpu

[Cristian Augusto]

Olá pessoal,

Agora pouco percebi que o processo "ksoftirqd/1" estava a utilizar metade de toda a máquina. Alguém já houviu falar deste processo?

Realizei uma pesquisa no Google, porém não achei muito a não ser assuntos relacionados a bugs

Alguem sabe do que se trata?

Abraço!

Acabei de ler, e verifiquei o uso de banda do servidor

Já entendi o que aconteceu.

Agradeço

Why is ksoftirqd/0 process using all my cpu?

I was feeling ubuntu was running a bit sluggish, and then I went to see the processes running on it, and found one which was using something like 50% of cpu called ksoftirqd/0. Does anyone know what this process does, why it is using so much cpu and how to make it less cpu-intensive. Thank you.

Your computer communicates with the devices attached to it through IRQs (interrupt requests). When an interrupt comes from a device, the operating system pauses what it was doing and starts addressing that interrupt.

In some situations IRQs come very very fast one after the other and the operating system cannot finish servicing one before another one arrives. This can happen when a high speed network card receives a very large number of packets in a short time frame.

Because the operating system cannot handle IRQs as they arrive (because they arrive too fast one after the other), the operating system queues them for later processing by a special internal process namedksoftirqd.

If ksoftirqd is taking more than a tiny percentage of CPU time, this indicates the machine is under heavy interrupt load

ksoftirqd is a per-cpu kernel thread that runs when the machine is under heavy soft-interrupt load.So, it is not eating your cpu but rather reducing your IRQ load.

A solução? Um bom firewall, e principalmente um servidor potente.

Já estou providenciando isso :)
