I'm having trouble interpreting this table.
Column 1: # of clients
Column 2: TPS using 9.1beta2 unpatched
Column 3: TPS using 9.1beta2 + fastlock patch
Column 4: TPS using 9.1beta2 + fastlock patch + vxid patch
Column 5: ???
At any rate, that is a big improvement on a system with only 8 cores.
I would have thought you would have needed ~16 cores to get that much
speedup. I wonder if the -M prepared makes a difference ... I wasn't
using that option.
