(darwin-legacy pretest) about 5% slow-down of \edef in etex

I am a bit rusty on this.

First, for info running the ./Build script ends up in this error

I then build directly only pdftex (skipping details)

first with :

$ ../configure --disable-all-pkgs --enable-pdftex -C >&outc

later with

$ ../configure --disable-all-pkgs --enable-pdftex -C CFLAGS=-Os CXXFLAGS=-Os >&outc

but do I get that right?

After copying the binary to suitable location and rebuilding pdftex.fmt and etex.fmt
timing of the test file originating this thread gives

real	0m2.306s
user	0m2.289s
sys	0m0.014s


which is far worse than the binary you compiled for pretest (1.7s)

However in the past (2 years ago) building locally via ./Build
gave faster binary. I probably have my configure flags all wrong.

I think I remember that last year I compared with local build
and the TeXLive2019 darwin-legacy one was only slightly
slower so I decided it was not the trouble building myself.

On the other hand my self-compiled TeXLive2018 pdftex binary
on the same test file (invoked via etex) gives

$ time etex testspeedbinaries
This is pdfTeX, Version 3.14159265-2.6-1.40.19 (TeX Live 2018) (preloaded format=etex)
 restricted \write18 enabled.

(./testspeedbinaries.tex . . . . . . . . . . )
No pages of output.
Transcript written on testspeedbinaries.log.

real	0m1.461s
user	0m1.446s
sys	0m0.012s

This is from /usr/local/texlive/2018/bin/x86_64-apple-darwin13.4.0
which was obtained from ./Build with a checkout of the TeXLive sources
around March 29, 2018 (looking at the file dates)

But, currently I fail in running the ./Build

Thanks,
