I have a Dual 1.25 GHz G4 here that I just got and I'm getting between
3.5 Mkeys and 5.0 Mkeys on OS X.2

I installed the 

dnetc v2.9001-478-CTR-02112023 for Mac OS X (Darwin 6.2).

and as it started up these lines appeared

[Dec 03 12:31:20 UTC] Automatic processor type detection found
                      a PowerPC 7400 (G4) processor.
[Dec 03 12:31:20 UTC] RC5-72: Running micro-bench to select fastest
core...
[Dec 03 12:31:33 UTC] RC5-72: using core #0 (ANSI 4-pipe).


I waited for it to slog through the first block and was surprised to
find that it managed under 1 million keys/sec.

RC5-64 ran on this machine (dual 450 MHz G4) at up to 8,000,000
keys/sec.

does this new RC5-72 not use the AltiVec unit in the G4?

Wondering

Roger
