LuaJIT has different limits and different design constraints. For a single table that consists only of constants there's effectively no limit (memory is the limit). But your test case has lots of small, nested tables. Every individual table only occupies a single constant slot (and not one for each of its keys/values). But there are too many of these tables to keep them in a single function. The short term solution is to split the table construction into smaller pieces, wrapped into individual functions. The long term solution would be to add a workaround for these limits to LuaJIT. But I'm not sure about the best way, yet. > [2] The Lua bug it exposed has since been fixed > http://www.lua.org/bugs.html#5.1.4-6 This problem is not present in LuaJIT 2.0. --Mike
