Karl, could you please rebuild the TL LuaTeX binaries with -O3 for
x86_64-linux? I committed (r68135) the binaries from Norbert's last autobuild on github for TL23: https://github.com/TeX-Live/texlive-source/releases/download/build-svn66984/texlive-bin-x86_64-linux.tar.gz The version number/devid were the same. I hope this was the right thing. --thanks, karl.
