One of the reasons VL is a bit faster than some other distros is that by default it loads only minimal services at default - only those necessary to run a workstation effectively. You can check all process running on your machine with the command "ps aux". The first 25 or so processes are kernel processes, denoted by the command [xxx] . The next few down the list (e.g. /usr/sbin/syslogd), if fact, anything there ending in a "d" - indicates a daemon service that can be turned on and off.
You are advised to keep syslogd, klogd, crond, inetd and ifplugd running. If you don't do printing you can turn off cupsd. If you don't communicate between Windows and Linux machines using Samba you can turn off smbd and nmbd.
You can turn these services on and off easily using Programs, VASM, SERVICE, SRVSET, 4, and turn on and off whatever you want there. Turning stuff off does decrease boot and shutdown times (probably by a second or two) and decreases RAM usage.
