Well, I did post a small benchmark here :-D
The G4 is definitely showing some muscle and that is even without altivec support in dnetc (which I am working on with some other developers to try to get into the dnetc client)  :-P


What do you mean? You're using the 2.9001 client, and OGR calculation has been using AltiVec since 2.8011, and you obviously get "AltiVec enhanced" rates.
AltiVec support for OGR has always been in the PPC Linux client AFAIK, since OGR support was added so late in this neglected branch compared to the x86 and MacOS PPC versions... :(

Yes, for the CPU's that the client recognizes (ie. the ones that has been added to the source of the client).
And it has to be compiled via an Altivec enabled compiler AFAIK.


But you do use a supported CPU (this is the Teron PX with an 800 MHz 7451, right?), and you do get the same result as other AltiVec enabled clients on the same CPU in the dnet client speed database.
BTW, the client supports AltiVec without being recompiled  (dnet only distributes binaries anyway, don't they?).

The remarkable thing about your "benchmark" (yeah, dnetc runs are largely meaningless to measure anything else than "how fast can this CPU crunch RC5 keys and OGR nodes?" ;) ) is that the 2.4 GHz P4 sucks so abysmally on OGR!
On the ~1.75 GHz Athlon box here I get about 13 Mnodes/s. Per processor... :)
