The problem I highlighted is that the average UPDATE latency is x2
what it is on current HEAD. That is not consistent with the reported
TPS, so it remains an issue and that isn't obvious.

I'm asking for detailed timings so we can understand the latency
issue. I didn't ask for a microbenchmark.
I celebrate your results, but we do need to understand the issue, somehow.
