The TT section + (up to 512MB) is the main memory; the ST section (up to 4MB) is + accessible to the built-in graphics board, runs slower, and is + present mainly for backward compatibility with older machines. + + This enables support for using (parts of) ST-RAM as swap space, + instead of as normal system memory. This can first enhance system + performance if you have lots of alternate RAM (compared to the size + of ST-RAM), because executable code always will reside in faster + memory. ST-RAM will remain as ultra-fast swap space.
