Slow for me, but not nearly as bad as for you:

One thing I noticed was that you and I are both using BerkDB 4.4.20 while
Jesus is running 4.7.25. I can't get to 4.7.x with MacPorts, but I can get
to 4.6.21. I installed that, rebuild bsddb with it and reran the tests:

Hmmm... Those extra six tests are expensive! I noticed there was a fair
chunk of time where the CPU meter showed the CPU essentially idle and the
dots were not moving. I trust it was waiting for the rather modest disk on
my laptop.
Next stop, in-memory disk (all commands as root):
hdid -nomount ram://1024
newfs /dev/rdisk1
mkdir /tmp/mem
mount /dev/disk1 /tmp/mem
chmod 1777 /tmp/mem
and rerun the tests with TMPDIR pointing at /tmp/mem. Whoops, it looks like
test_support creates temp files in the current directory, ignoring TMPDIR or
tempfile.gettempdir(). (Why is that???) So, cd to /tmp/mem first. Whoops!
Again, the bsddb tests force the test database into /tmp. Fix test_all.py
to use TMPDIR if set. Damn! 1gb isn't enough. I tried boosting it to 2gb.
Still no go. Jesus, how big is your ramdisk?
Here's a couple line patch for bsddb/test/test_all.py that uses TMPDIR if
it's set.
