It works quite fast in a FIFO mode (buffering), but when there is no buffering and each operation must be performed immediately, if falls down with a perforance. You can always try to use a direct access to the com ports (bypassing an emulation) but it is not something that is recommended for the real use. Try setting $_hogthreshold to 0, maybe that will help a bit. Btw, what dosemu version do you have? The latest ones shold perform a little better under some conditions.
