I think what would be helpful here next is a self-contained benchmarking
script. You posted an outline of what you did for the original version
at

It doesn't sound like it would be hard to turn that into a little shell
script. I'd rather see one from you mainly so I don't have to worry
about whether I duplicated your procedure correctly or not. Don't even
worry about "best of 3", just run it three times, grep out the line that
shows the TPS number, and show them all. One of the first questions I
have is whether the performance changed between there and your v5. A
self-contained and fully automated performance test case would ease
review, and give some performance regression testing for other suggested
changes to use as a reference.
