If your computer has a large amount of memory, you can run jEdit in background mode by passing it the `-background` command-line switch. In background mode, jEdit will stay running and in memory even after all views are closed. This avoids the startup delay associated with starting jEdit multiple times.

If you also specify the `-nogui` switch, an initial view will not be opened; so jEdit will load, but remain invisible until another client instance is started. Using this switch, you can have jEdit loaded when your computer starts, ready for use later on.
