It adds DPMI functionality support to QEMM. No speed advantage at all.

BC++ 3.1 does require DPMI support. If it finds none as it loads, it
loads it's own, which it removes on exit. This is documented
(somewhere) in the manuals.

If you have QDPMI loaded, it uses that rather than it's own DPMI
support. So far I find the Borland driver 100% reliable whereas the
QDPMI driver falls over on large multimodule compiles running from a
makefile.
