VCs are a great way to free up memory. Most Linux distributions run
about 6 of them out of the box. On average running 6 VCs requires about 4MB of
memory. Removing a couple of them can free up a couple MBs of memory. Most
users can get away with running only 3 or 4 VCs. How many you choose to remove
is a matter personal preference. Just remember that the fewer you run, the more
memory your applications will have to run.
The file which outlines how many VCs get loaded is
/etc/inittab. In order to remove VCs:
Load /etc/inittab in a text
editor.
Look for a line which looks like the following line (the key
feature being a line which starts with c1):
c1:12345:respawn:/sbin/getty tty1 38400

Start at the highest number (i.e. c6) and comment it out by
inserting a '#' in the first row. Repeat this step as many times as needed.
Remember every line you comment out is one less VC running.
Re-boot the system for your changes to take effect.
