Aye, there's the rub.  CPU emulation is slow, but I/O emulation is really slow.
But I'm looking forward to Hercules 4.0, which promises an I/O subsystem
restructure, which should help in that regard.  Incidentally, the version
of Hercules currently packaged for Debian, 3.07, was released by upstream
more than five years ago.  There have been many enhancements, performance
improvements, and bug fixes since then.  I'd love to see the Debian hercules
package updated.  The current production upstream release is 3.11, released
on September 15, 2014.  3.07 was released on March 10, 2010.
