Re: LuaHBTeX from TL26 is significantly slower than in TL25

Hello,

I downloaded the luahbtex binary(A) from ConTeXt Bulid farm 
https://build.contextgarden.net/#/builders/40/builds/144 and I compared 
it with the binary(B) from TeXlive pretest 2026. The result: the 
binary(A) is OK, the processing time is comparable with luahbtex from 
TeXlive 2025. The biary(B) is slower (almost two times) as I reported 
before.

Applying the file command to binary(A):

luahbtex: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), 
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, 
BuildID[sha1]=cc9bfc6319593228d3f0cf7142c796c3d55b3746, for GNU/Linux 
2.6.32, stripped

Applying the file command to binary(B)

luahbtex: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), 
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, 
BuildID[sha1]=6f438fa29895e28d3a33aa6b9d61cd97a125c6d4, for GNU/Linux 
3.2.0, stripped

ls -lh luahbtex (binary(A))

-rwxr-xr-x 1 olsak olsak 9.1M Feb 15 14:29 luahbtex

ls -lh luahbtex (binary(B))

-rwxr-xr-x 1 olsak olsak 15M Feb  11 22:49 luahbtex

Note: 9MB versus 15MB.

It seems that the problem is related to settings of compilation 
environment when a binary is built. Can someone tell more about it and 
correct the build options for TeXlive binaries?
