NetBSD recently added tmpfs, as a replacement to mfs.  This also may be
worth looking at, if it performs better.  (though mdconfig is a tool and
tmpfs is a file system, so these are really two separate but related
topics)

For tmpfs, there's some benchmarks here, vs. NetBSD's existing mfs:

Code's here:

I've had a recurring geek fantasy over the years of buying a motherboard
and maxing out the installed RAM, and using most of that as a filesystem
for buildworlds.

Gigabyte was recently selling a PCI card with several gig of
battery-backed RAM on it for use as a drive - relatively expensive, of
course, even with how much RAM has dropped in price over the years.
