Re: [aspectj-users] On the subject of profiling
|
Hi Dave,
The world will be big - and gradually I work on shrinking it. The
problematic object that surprised me is the model (discussed under
https://bugs.eclipse.org/bugs/show_bug.cgi?id=278496). There are a
few things I plan to do to address it during 1.6.7.
In an ideal setup the World will shrink when not being used and grow
as necessary, pulling back in type information. But it was never
designed like that in the first version of AJ and because it is a core
piece I have to be careful what I do with it. In my blog post on LTW
memory usage ( http://andrewclement.blogspot.com/2009/04/aspectj-load-time-weaving-and-memory.html
) I describe a couple of flags that can *probably* also be used with
compile time weaving to reduce the world size - but they haven't had
enough testing for me to feel comfortable having that behaviour
default to enabled.
