DOS ain't dead

DOS copy command (Developers)

The default DOS "cache" is controlled by the BUFFERS statement in CONFIG.SYS, so playing with that setting will probably make a huge difference in how fast everything works (assuming you're not using an external cache like SMARTDRV or LBACACHE or ...).

Also, according to MS-DOS 6.2 HELP, you can give BUFFERS two different numbers:

BUFFERS=n[,m]

where m is the size of the secondary cache. Does anybody have any idea how MS-DOS uses a two-stage cache? HELP doesn't really explain it, but indirectly refers to the secondary buffer cache in the context of SMARTDRV (and possibly double-buffering?).
