Hey hey!
I'm about to start using Terra for a pretty large project and I was
wondering a little bit about the status and plans for profiling support
for Terra that exists now and that's coming up in the future. LuaJIT 2.1
has added support for profiling and it's proven essential to figure out
how to make code run faster. I was trying to benchmark luajit with
minilight (http://www.hxa.name/minilight/) comparing it to the
performance of C. It was about 10x slower and when profiling it seemed
to be due to it pretty much not using the JIT at all, instead always
falling back to the interpreter because of the current register handling
in luajit.
So when using Terra it would be super useful to be able to figure out
where LuaJIT is doing things the wrong way, so that I can replace the
troublesome functions with terra functions instead. Which would allow me
to easier balance using (possibly) more productive high level code a lot
of the time without sacrificing control of performance.
As such, I'm wondering if the LuaJIT 2.1 profiling support will be added
to Terra when it's finally released, and also if maybe Terra has any
plans for profiling Terra code to find hotspots etc. Something that
could also be useful.
Thanks!
Best regards,
Isak Andersson
