Quite logically the less nonessential services (software) you start at the boot, faster your system will boot.
First of all, open the PCLinuxOS Control Center:
Startmenu -> Configuration -> PCLinuxOS Control Center.
Start the "Configure the System Services" tool from the "System" tab.
You see a whole list with names, buttons and checkboxes. Depending on what software you have installed this list will slightly differ. And what you should be running and shouldn't depends on your system and on your preferences.
How do you tell which are essential and which are not? It is easy, if you see any service with the "On boot" checkmark with stopped state, it is a non-essential.
In my case:
hplip, since I don't have any hp printer.
mdadm, since I don't have any raid device,
acpi and acpid, since I boot with acpi=off.
If you don't know what the service is doing the info button will give you a short explanation, but clearly if the service marked stopped with the boot checkmark, it can't be essential otherwise you would not be able to boot.
Next you might want to mark some services started on boot, that's strictly your preference and it requires a little bit of research. I marked the dkms service (since I want it to automatically recompile the nvidia driver if I change a kernel) and I marked the sshd service, since some times I want to take over my home machine from the office.
More information about the services
The services you might find in your services list, with a little explanation. Note that if your computer is running fine as is, you don't have to turn on any extra services.
Laptop services
acpi - For laptop use, gathering information about the temperature and state of the fans.
acpid - See above.
apmd - Battery status on laptops.
pcmcia - Plug-and-Plug on Laptops. No laptop? Then not necessary.
numlock - If you like your Numlock switched on during boot?
Printer services
cups - Printing services - do you like to print every now and then?
hplip - HP printer drivers. No HP printer? Then not necesarry.
hpoj - see above.
mtink - For Epson Printers.
oki4deamon - OKI 4w WinPrinter support.
xprint - XPrint servers - ?
Networking Services
iptables - The firewall. Probably turned off if you are running Shorewall or Firestarter.
lisa - The Lan Information Server
netfs - Network File Systems, Windows (SMB) Networks, etc.
network - You want internet?
portmap - Port Mapper. If you run a network or networkserver, you'll need this. Otherwise not!
pppoe - For ADSL Internet. PPP over Ethernet.
pptp - ? Manages network settings when rebooting
saslauthd - SASL Auth deamon - ?
slpd - The deamon for the Service Location Protocol - ?
sshd - SSH service deamon. (Secure networking)
tmdns - DNS responder, for zeroconf environments.
vncserver - Remote X Administration. Not secure though! Know what you are doing!
wlan - Wireless Lan??
xinetd - For running servers.
Sound services
alsa - Sound drivers. If you sound is going and these are off, keep them off.
alsasound - See above.
sound - The sound driver!
Misc Required services
atd - You can schedule software to run at a given time. If you want this, keep this turned on.
crond - You can schedule software to run at a given time repeatedly.
dm - The graphical login manager - you need this.
haldeamon - For using (and seeing state changes in) your hardware. Turned on.
keytable - Setting up your keyboard. Keep that on.
messagebus - This software communicates internal hardware changes. Keep it on.
xfs - The font server. You need this for getting text on the graphical screen.
shorewall - Your firewall. Default firewall for PCLinuxOS
Misc services
These should probably be in the lists above somewhere.
cpufreq - Probing cpu frequency scaling - ?
daild - On demand automatic dialup internet facilities.
gpm - For using your mouse on the text based terminals/console.
kheader - Automatic generation of kernel header - ?
mdadm - When running RAID devices - No RAID? Turn it off.
partmon - Checks to see if your partitions (harddisks) are almost full.
pcscd - ?
powernowd - Frequency setting - ?

This list needs more work!
