Hello
I installed TL pretest 2026 a tried to run LuaHBTeX 2.24 with OpTeX
macros. I noticed, that LuaHBTeX 2.24 (TeX live 2026) is significantly
slower than LuaHBTeX 2.22 (TeX live 2025). Why?
For example time optex optex-doc does:
This is LuaHBTeX, Version 1.24.0 (TeX Live 2026)
restricted system commands enabled.
(/home/olsak/texmf/tex/optex/doc/optex-doc.tex
...
real 0m17.367s
user 0m16.836s
sys 0m0.429s
but time optex optex-doc with TL 2025 does:
This is LuaHBTeX, Version 1.22.0 (TeX Live 2025)
restricted system commands enabled.
(/home/olsak/texmf/tex/optex/doc/optex-doc.tex
...
real 0m9.676s
user 0m9.205s
sys 0m0.361s
Regards
Petr Olsak
