Well, this is not an OpenStep issue directly, but the loss of ObjC++ was
a *HUGE* hit for me. I discovered this after buying a new iBook to
start porting all my C++ frameworks from Linux/Solaris to MacOS X. It
took the wind out of my sails.

I have no idea as to the reason(s) behind the performance issues, but
there is definitely a slower feel to it. My old NeXTstation color
running NEXTSTEP (2.1-3.3) on a 25 MHz (?) 68040 with 16 MB RAM seems
comparable to my new iBook running on a 500 MHz PowerPC G3 with 384 MB
RAM. In fact, a few user-level operations such as re-sizing a window on
10.0.x feel *much* slower. (Note: NEXTSTEP only resized the frame).
With absolutely *no* knowledge <grin>, I just chalked the performance
hit to Apple having to rip out DPS and develop a new imaging model
virtually from scratch.
The performance from the 10.1 demos look great however, and if Apple
brings back ObjC++ at about the same time, I will be a very happy
camper. Now if we could just get some good books for Cocoa ... (yes, I
have Learning Cocoa).
