No, I'm not sure what's causing this yet.

cvs2svn creates one dumpfile per revision now, loads that small
dumpfile, removes it, then continues on to the next. We used to do
one huge dumpfile, but this meant cvs2svn's peak tmp space
requirements were very high, so we changed.

Try running with --dump-only, then create a fresh repos and svnadmin
load the dumpfile. Does that go faster?
