IDLEHALT=1 halts the CPU (with a HLT instruction) before calling Int28, when the kernel is waiting for a key to be pressed. FreeDOS's default Int28 handler itself does nothing. FDAPM however might execute another HLT in its Int28 handler resulting in bad performance. You'll get the best performance with no HLTs at all, but one HLT before/in Int28 (IDLEHALT=1 but no FDAPM?) shouldn't affect performance badly either. That might be related to how exactly the application writes to the screen.
