On the other hand - the OSX version of the distributed client does only 35,045,989 nodes/sec on a 2,7 GHz G5 (vs 42,445,595 for the MorphOS one), so the client version does count.

And yes, I had the CPU option set to max performance in OSX settings (when set to "reduced" it gave me a humble 27,875,515 nodes/sec).

...aand I've made those PC3200 DDR RAM benchmarks (for now only on OSX, MorphOS a bit later). The results are very interesting.

dnetc for OSX 1,8 GHz, PC2700: 7,044,871 nodes/sec (Only 20% of the 2,7 GHz speed)
dnetc for OSX 1,8 GHz, PC3200: 14,365,629 nodes/sec (More than twice as fast! Almost 41% of the 2,7 GHz speed)
