I would like to understand the root cause before making changes.

"It's faster when I do X" is useful information but it doesn't
necessarily mean doing X is the solution. The "it's faster when I do X
because Y" part is missing in my mind. Once there is evidence that shows
Y then it will be clearer if X is a good solution, if there's a more
general solution, or if it was just a side-effect.

I'm sorry for frustrating your efforts here. We have discussed a lot of
different ideas and maybe our perspectives are not that far apart

Keep going with what you think is best. If I am still skeptical we can
ask someone else to review the patches instead of me so you have a
second opinion.
