OK, this is a repeat sort of, but I've changed the speed of my Celeron to 920 and ran the benchmarks so I thought I may as well post them.
[Aug 06 22:04:58 UTC] Benchmark for RC5 core #2 (RG class 6)
0.00:00:16.39 [2,622,419.42 keys/sec]
[Aug 06 22:05:17 UTC] Benchmark for OGR core #0 (GARSP 5.13)
0.00:00:16.08 [6,354,923.94 nodes/sec]
[Aug 06 22:05:45 UTC] Benchmark for RC5 core #2 (RG class 6)
0.00:00:16.39 [2,622,739.38 keys/sec]
[Aug 06 22:06:05 UTC] Benchmark for OGR core #0 (GARSP 5.13)
0.00:00:16.06 [6,359,669.67 nodes/sec]
[Aug 06 22:06:30 UTC] Benchmark for RC5 core #2 (RG class 6)
0.00:00:16.40 [2,621,140.34 keys/sec]
[Aug 06 22:06:49 UTC] Benchmark for OGR core #0 (GARSP 5.13)
0.00:00:16.09 [6,349,790.72 nodes/sec]
So that's still 6,354,794.78 nodes/sec and 6,907.39 nodes/sec/MHz in OGR.
And, that's 2,622,099.71 keys/sec and 2,850.11 keys/sec/MHz in RC5.
By the way, OGR-25 should be the same speed for processing right? ie. a node is the same size right? The reason I ask is with the humungous sizes of these work units I have no real idea how fast my computer is working.
