You probably run a 64-bit linux. In 64-bit mode, the processor can't run
realmode or
16-bit dpmi applications, so dosemu has to emulate the binary programcode.
If you have got an diskimage with an window on it, you could run that
image in kvm.
On my machine, clipper code with many accesses to disk is much faster
when run with kvm
than in dosemu.
The other option would by to run a 32-bit linux, perhaps from a life cd.
