cpuspeed - RHEl daemon

[Sushobhan Das_1]

RHEL 4 OS comes with a daemon called "cpuspeed" and description given below is what i found from internet. My question is - keeping this daemon alive in RHEL 4 installed on a Proliant DL360/380 G4 adds any value or not?

-----------------------------------------------------------------------
RHEL daemon name: cpuspeed
Summary: CPU Frequency adjusting daemon.
Description: cpuspeed is a daemon that dynamically changes the speed of your processor(s) depending upon its current workload if it is capable (needs Intel Speedstep, AMD PowerNow!, or similar support).

Shalom,

I've noticed no difference whether its running or not. Not on high load systems, not on low load systems.

I'd say turning it off will not hurt at all.

Thanks.

I was googling little on this & found that this daemon may add value on a notebook. However I wonder who is going to install RHEL on a laptop.

Shalom,

On a laptop, especially with vmware it may be advisable to use it.

Often with vmware there are cpu speed reporting issues that this daemon can help with.

cpuspeed is just for power saving on laptops when CPU isn't busy. You don't need it on servers.
BTW, there are a few others services, that I suggest to "check off" on servers - like pcmcia, apmd and more.
