Tom,
Correct. This is a scalability patch rather than a performance patch,
although each aspect is related. I would expect the gain to be better as
more cores and users are added.
I can run some tests along the following lines:
1. NUM_BUFFER_PARITIONS sizes for 16, 32, 64, 128, 256, 512, 1024, 2048.
2. Cores set at 1, 2, 4, 8, 16, 24 and 32.
Does anyone have any comments or suggestions?
David
