Rhapsody and OPENSTEP Benchmark Suite
___________________________________________________________________________________

Release Notes NXBench 2.3 

This release is nothing more than a quick port of the well known NEXTSTEP NXBench 
to Rhapsody and OPENSTEP Mach. In addition, Uptime Inc does no longer maintain a
spec list. So please don't send us emails filled with your machine's specs! Although if somebody wants to maintain such a list in the meantime, we will give 
him mental assistance...;-)

This release contains the following new features or fixes:

· Rhapsody DR1 PPC and x86 are now supported
· OPENSTEP Mach x86, m68k and SPARC are now supported
· Dhrystone is now usable for faster CPUs again.

Dhrystone 2.1 

This is the unmodified version 2.1 of Reinhold P. Weicker. It's run new with 
4'000'000 iterations and compiled with registers and -O2.

NXFactor 2.1

NXFactor benchmarks the graphic functions of the NEXTSTEP Window Server. It's 
interesting how the different categories perform on different graphic and bus 
systems.

This is an artificial benchmark. It tests many different functions of the window 
server which all have the same weight for the calculation of the mean value.

All values are normalized to the reference machine,  a NeXT cube with the 
following configuration: 

				25MHz 68040
				28MB RAM
				2 bit Grayscale Video 
	
Due to certain optimizations, the benchmark does no longer give 1 on those machines, though.

Note: The Graphics Benchmark depends a lot on window ordering. please command double click the app to ensure that the benchmarkwindow is the only window on screen. it's the only way to get meaningful results.

TODO

There is nothing more to do for us since this is the ultimate last official release of NXBench!
Technology from this app will be used whithin the forthcoming Benchmark Suite from 
MiscKit, so it won't die.
