Can you share any results from prototype testing?
I'd prefer not to just yet as I don't want to raise expectations unduly.
When testing I was using a simple local benchmark, whereas
I'd prefer to run something more official such as TPC.
I'm also missing a few required features in the protoype which
may affect performance.
Hopefully I can can provide some results soon, but even those will
be unoffical.
Neil.
