The performance difference beats me. Here is a test I did today :

I compiled equalizer both with and without paracomp (essentially your
latest commit). And ran the benchmark. Virtually no difference.

Can you sending me the following - 

On your system, note down the command line that is used to compile
compositor.cpp (from Equalizer).  Also note the command line that is
used to compile compositecpu.cpp (in Paracomp). Then send me both lines.

Additionally, (if you can try this!), compile equalizer with
optimization enabled & debug symbols enabled (equivalent to "-O<n> -g").
Do the same with Paracomp - by adding a "-g" to the "-O<n>".

After that, run "objdump -dS compositor.o" and "objdump -dS
build/compositecpu.os" and get me both outputs.

That's the best approach I can think of at the moment...

Thanks for your patience !
