best option for profiling lua code? (lua/luajit)

[Emmanuel Oga <emmanueloga@...>]

Hey, I already tried the alternatives provided on the wiki [1]. So far
I obtained the best results using the Pepperfish Profiler. The thing
is that the output is not very good for my purposes, and before trying
to fix that myself I'm wondering if there is already a better pure lua
profiler out there (both in the sense of speed and niceness of the
output).

In the other hand I'm wondering if anybody tried to link google
perf-tools [2] into a lua interpreter?
Finally I'm wondering if luajit2 provides any functionality built in
for profiling (I figured out it might since other VMs include such
features but I could not find anything about that in the luajit docs).

Thanks!
