Re: [aspectj-dev] Profiling AspectJ Performance impact

["Ramnivas Laddad" <ramnivas@xxxxxxxxxxxxxxx>]

Rob,

You may want to read the following paper (particularly section 7)
http://hugunin.net/papers/aosd-2004-cameraReady.pdf

Note, however, this paper is from 2004 and as Eric notes, implementation has been further optimized since.

Thanks Eric, that's very useful. That was actually what I planned to do in  a very simple prototype, implement 2 versions, one in pure Java and one using AspectJ. If there is very little overhead it may not be worth it.

 

Thanks again

Hi, Rob.

We have don a lot of such measurements. I often use JProbe for this.
However, the question is first of all what you want to measure. An
aspect implements functionality. So if you don't implement it with
AspectJ, you have to implement it with pure Java. Hence, to make a
fair comparison you actually need a second version written in pure
Java. Experiments in the past have shown that if you do so, the
overhead is negligible (some very few percent) and since then it has
been even optimized more.
