Unessacary Proccesses in Redhat

witnessmenow

Hi Guys,

Sorry to keep bugging ye with stupid questions, but i have to try optimize performance out of a machine and i was wondering if any of ye could suggest somewhere where i can find a list of default process started by redhat and which ones are essential?

Thanks alot.

chkconfig --list will give you all the services loading up at boot time

You could also have a google for removing modules from your kernel which would speed up boot time as well.

do the chkconfig as greenhell said and post the results here or in a pastebin, then we can see what are the unecessary ones.

Is this machine going to be a server or staying as a desktop?

witnessmenow

Neither

I cant go into it too much , but basically take it as a desktop.

Thanks

To cut down on most things I would advise running in runlevel 3 anyway, you can still start x when necessary. I dont think you need the following

acpid
bluetooth
cups
isdn
nfslock
smartd
yum-updatesd

There might be a few others, I use suse so turning some of these off my drive it nuts, but hey its all trial and error .

Also if you deal with lots of small files on this machine you may want to consider using xfs for the partition thats messing with lots of small files.

djmarkus

I really do recommend you keep yum-updatesd(software updates), smartd(hard disk failures), and acpid(interfacing with ACPI) and nfslock if you're going to be using nfs.

witnessmenow

Well Yum is definitly a goner! As the Application I'm running performance drops every hour basically, and i presume thats whats causing it.

Files arent a big issue on this, Its all I/O processing

Thanks for the advice lads

EDIT:Also just had a look, runlevel 3 and 5 are basically identical bar one thing.

GreenHell

A mouse?

Not having the X server running should free up processor and memory.

Your logs should tell you why your app is dropping, I can't think of one reason by yum would effect any other app. Well maybe if its auto updating, but by sounds of it I doubt you have it setup that way.

Thanks for your replies guys.
