are all processes running in linux required
 

Hi,

I have installed Linux, mainly bcos of the fact that MS is slow!!!!! (and the environment too).

I have installed Mandrake 9.2.

I get a feel like the system is slow in response, especially menus and when i see the system monitor, it says cpu usage 10% on an average.

I am pasting below the processes running n my PC. Pl let me know if all these processes are required and how can I tune up the system for performance?

You can stop safely these:

dhclient --> DHCP client ? Not very neccesary unless on a network.
portmap --> Not neccesary but for NFS network services ,.....
ypserv --> Not very neccesary unless on a network.
rpc.ypxfrd --> Not very neccesary unless on a network.
atd --> Task planner. You'll learn it later.
named --> DNS server. Too much ....
rpc.yppasswdd --> Not very neccesary unless on a network.
httpd2 --> Apache webserver.

Also you can get into kde control center and stop some services under Components - Service Manager.

Hey u beter install fedora on ur pc....
Its quite fast.
I am going to install tomorrow

Yes,I think Fedora would be a good choice too.Specifically the version that "CCRMA" at Stanford University has. You can download the ISO's fron their website. It's a modified version of Fedora in as much as it is used for music and video production tasks which require lower latencies and higher scheduling priorities,etc.. However, without all the tech speak the system as a whole is nice and snappy. All you need to do is look up "CCRMA" on the google search engine. The instructions are very detailed and most anybody should have no problem setting up the system.
