>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. </P
