To be fair, though, how many DOS games need a Pentium or better? (I don't really know of any, but I'm no games expert. I bet Udo Kuhnt would know, though.)

Try backing up and then fiddling with the config file (DOSBOX.CONF). Also try frameskip.

Yes, definitely that would help. Do you know what compiler your build (or even the official) uses for Windows? Because MinGW uses an older GCC (and even only recent did GCC implement optimizations for Core2). Last I checked, there was a beta GCC 4.x on SourceForge:

GCC Version 4 Technology Preview: gcc-4.2.1-sjlj -2 August 14, 2007

If you're adventurous, you could try rebuilding it yourself. Or nag the official Windows builder to upgrade his setup.
