[aspectj-dev] FW: [aosd-discuss] Performance Studies on AspectJ
|
These guys use an extended ajc that tags bytecodes and a JVMPI-based metrics
analyzer. I wonder if it is possible to integrate something like that into
automated performance metrics that run with the build.
Bytecode performance aside, for any 1.2 changes to the ASM I'm interested in
keeping tabs on compile-time performance (after this summer's canonical path
experience).
Adrian: didn't you have some automated way of comparing compile times? Did
you end up checking it in?

Subject: Re: [aosd-discuss] Performance Studies on AspectJ
In recent work we have started the process of defining appropriate
dynamic measurements and dynamic metrics to evaluate the performance
and behaviour of AspectJ programs. We have applied our approach on
a selection of benchmarks to illustrate our ideas, and we can show
some potential performance bottlenecks.
A significant portion of the bottlenecks can be avoided by adopters
who have an appropriate understanding of the current AspectJ best practice,
others can be improved via compilation techniques. Our tools are intended
to help extend such understanding for particular applications by exposing
the
bottlenecks to the users and compiler writers.
Clearly this is only a start, and we continue to work on our ideas
and make a more comprehensive set of benchmarks and metrics. We are
welcome to comments, and also would greatly appreciate more benchmark
programs.
A technical report version of our work is available at:
