RE: [aspectj-users] ajc performance

["DiFrango, Ron" <ron.difrango@xxxxxxxxxxxxxx>]

Title: Message

Mark,

 

I would say no!  In my experience, ajc does take longer than javac.  In our system it takes around at least 3 to 5 times as longer to compile the entire project with ajc.  In order to mitigate this time, we use the listing file mechanism so that ajc only processors those files that are affect by our aspects.

 

And before any one says this is bad we are talking a 2 to 3 minute build using this two-phase approach versus a 10 to 15 minute build time with ajc.  This is significant over the course of a day when you are doing heavy development work.

 

I have not used jikes so I am uncertain of its performance relative to javac. 

Thanks,

Ron DiFrango

Subject: [aspectj-users] ajc performance

Is this statement pretty accurate?

"Compiling with ajc takes approximately the same amount of time as compiling with javac which takes about five times as long as jikes."

Is there any on-going work to speed up ajc?
