We did some pretty heavy performance testing of a particar application comparing 2.1.6 and 2.2.0 and 2.2.0 was slower in most cases. The testing was done on a Celeron533 128Meg RAM running RH6.1.

I am pretty sure (61%) that in the original release of 2.2.0 there was something about a speed increase. One talked about on single processor (20-40%) and the other was dual processor (60-80%). It partly has to do with that "one line of magic code" in the z2.py.
Ethan? Paul? DC? Care to shed some light?

Really? I didnt see anything about this in the Changes file... has
something
else changed I didnt see? I noticed that 2.1.6 wasnt making the best use of dual processors.
I thought only ZEO would make good use fo dual processors?
