- Please leave us alone with your benchmarks. Always remember: there are lies,
- bloody lies and benchmarks. Yours was one of the bloodiest benchmarks I've ever
- seen.
-
- Sorry, only serious. Your benchmark doesn't matter if you don't happen to
- calculate fractals all the time. The main question is: do you feel it while
- using DOS in OS/2? Do you really think, all the participants of this newsgroup
- are dump and even more slow than OS/2 or how do you explain why anyone uses DOS
- in OS/2 if the performance loss would be that large?
-
- Noone noticed until now, and if you think a little longer about your hardware
- configuration, you might notice that you used a 386SX, that means: a 16Bit CPU.
- Yes, 16Bit, try to imagine what happens if you do a context switch on a 32Bit
- architecture that is emulated by a 16Bit Bus. It really halves performance (if
- not more). And if OS/2 works in the background on the fly on a real 32Bit Bus,
- it crawls on 16Bit. Try the same on a 386DX and post the benchmark once more.
- Perhaps you will be surprised (perhaps we will be surpries, but I don't believe
- in this)
