I am running smp, 4.0-current, as of Mon Feb 15 03:34:29 PST 1999.
Printing is very slow. I have a HP LaserJet III attached to lpt0. Printing in the pcl, text, mode is slower than I expect. Printing in the postscipt mode is extremely slow. A 30K postscript file has been OVER 5 minutes and is not finished!
