Simply to comment that on the test file doing 1000 pages each with 1000 dots
I detect no real difference between your pretest binary (pdftex) and
the one I self-compiled from TeXLive sources with "-O2" compiler flags

It is only with test files doing many \edef that I see 5%-10% difference (in favour of self-compiled pdftex)

The Build script (which aborts due to ICU) has this buildinfo.log

This is how I decided to use "-O2" flags when building pdftex only.
