The configuration is strictly depending on the use of your PC. I try a few comments here after: acpi : keep it Advanced energy management keep it anacron: tasks scheduler (do you schedule services to be executed on your system?) atd : tasks scheduler (do you schedule services to be executed on your system?) auditd : Linux Auditing System Daemon, which collects security related events in a dedicated audit log. If this daemon is turned off, audit events will be sent to syslog. Requested by SELinux. Do you configure SELinux? autofs : keep it. To automatically mount devices / file systems avahi-daemon : This is a daemon which runs on client machines to perform Zeroconf service discovery on a network. avahi-daemon must be running on systems that use Avahi for service discovery. Avahi-daemon should not be running otherwise. cpuspeed: keep it (This script enables/disables processor frequency scaling support, either using the cpuspeed daemon or in-kernel frequency scaling support) crond : tasks scheduler (do you plan services to be executed?) cups : print management firdtboot: to be disabled (is it the first run of your system?) gpm : to use cut / paste haldaemon : keep it hplip : is a HP printer connected to your PC or network? libasm : ip6tables : firewall, keep it iptables : firewall, keep it irqbalance : The irqbalance daemon will distribute interrupts across the cpus on a multiprocessor system with the purpose of spreading the load (Intel Core 2 Duo, AMD X2). No impact on single processor isdn : to be disabled (your access relies on an Adsl connexion) jexec : keep it kudzu : do you frequently change your configuration? If not, disable it lm_sensors : to capture various information from hardware probes lvm2-monitor : did you configure a Logical Volume on your system? mctrans : requested bu SELinux mdmonitor : mdmonitor service checks the status of all software RAID arrays on the system. Does your system comprise Raid disks? messagebus : keep it micrrocode_ctl : keep it netfs : do you Mount and unmount network filesystems? nfslock: Mount and unmount network filesystems. pcsd : to support smartcard. portmap : no more use until NFS V4 rawdevices : readahead_early: keep it (to improve boot performance) readahead_later : keep it (to improve boot performance) restorecond : requested by SELinux rpcgssd :requested by Network File System rpcidmap : requested by Network File System sendmail : do you manage a mail server? smartd : disks supervision sshd : do you need ssh connection to your system? syslog : keep it yum : to automate the updates yum-updatesd : to automate the updates I hope it will help you tune your system ...
