Subject:Re: [groovy-dev] as usual on performance - operations on primitivesActions...

No, infortunately it is not what I am looking for. This part (how operations done) is very clear and consistent and call sites already appretiate all this rules.

My questions are: What's going on when we declare field of primitive type? What is field type in compiled code? Same for Local variable? Parameter? Return type? How magical boxing/unboxing work Etc.

I don't want to say right now there are some problems in this area. What I say I would love to read clear description, which will help to understand.

Alex

P.S. Unfortunately 30-40% is much less than I expected :(

Hello Alex,

I am happy to report some new (uncommited yet) progress with performance of numerical operations. Some tricks with call sites (partly based on John's ideas) lead to another 30-40% improvement for "our idiotic benchmarks".

Waoo, awesome :-)

There are some design issues in MCRegistry & ReflectionCache I will discuss and ask for advice in another email but now I want to ask on primitive types.

Could some Groovy expert describe me exact rules of work with primitives in Groovy. Of course, I can find that in compiler code (and obviously did that) but what I want is verbal description, which will help us to understand consistency/unconsistency and possible logical modifications.

What do you want to know exactly?

I think this page explains quite well how things like promotion and such work in Groovy, I guess it could answer your questions: http://groovy.codehaus.org/Groovy+Math

Is it what you're looking for?
