[luatex] LuaTeX precompilation

[Henrik Mannerström]

This thread turned into a debate over what is slow, what packages you should use and how old computers you can use. I’m re-posting my original question:

How hard would it be to make a luatex compatible precompiled format? One that basically serialises the whole luatex state to a file and could re-use
it? Would it speed up the compilation of short documents? Is there any plans or projects related to this?
