I am seeing the same thing with 2.2.2.  Rdump speed is about 45KB/s.
However, I have an identical machine that's still running 2.1.5 and it
rdump's at ~450KB/s.  I moved the 2.1.5 dump binary over to the 2.2.2
machine and it runs at ~450KB/s there, too.

I tried doing diffs of the two versions of dump, but there were a lot
of changes & I haven't had a chance to look at them.  You can probably
solve your problem in the short term by just installing the 2.1.5 dump.

Steve.
