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. -- Steve Caine :: shc@cfg.com :: http://www.cfg.com/ Caine, Farber & Gordon, Inc. :: Pasadena, CA, USA
