LuaJIT 1.1.5 vs 2.0.0-beta3 on C function calls

[Ilya Martynov <ilya@...>]

Hello,

We are embedding LuaJIT 1.1.5 into our own HTTP server so that we can
use Lua as a scripting language to write application business logic.
Recently we tried updating LuaJIT to 2.0.0-beta3 in the server and
noticed that it was actually 20% slower with our typical Lua programs.
On the first glance the main difference from benchmarks being
published so far on the maillist is that we have many C function calls
in our Lua programs, some being called in inner loops. So I was
wondering, could it be possible that LuaJIT 2 is actually slower on C
function calls then LuaJIT 1?
