No, I meant what I wrote there. When I ran the tests the HEAD included
the v25-0001 refactoring patch, but v26 did not yet exist.
For now, we are only performance testing the first
"Reuse-Tablesyc-Workers" patch, but not yet including the second patch
("Reuse connection when...").
Note that those "Reuse-Tablesyc-Workers" patches v24-0002 and v26-0001
are equivalent because there are only cosmetic log message differences
between them.
So, my testing was with HEAD+v24-0002 (but not including v24-0003).
Your same testing should be with HEAD+v26-0001 (but not including v26-0002).
