- Subject: LuaJIT-2 shootout performance one-core versus quad-core

Examining latest "language shootout" results at
http://shootout.alioth.debian.org/
I noticed a significant relative performance degradation when
comparing LuaJIT-2.beta on x86 one-core
http://shootout.alioth.debian.org/u32/benchmark.php?test=all&lang=all&box=1
versus x-86 quad-core
http://shootout.alioth.debian.org/u32q/benchmark.php?test=all&lang=all&box=1
On a single-core LuaJIT-2 looses to GCC 1:2 while on quad-core 1:7.
Is there any hope that LuaJIT will use multi-threading? After all, it
traces the execution and knows at run-time what paths are parallel.
