Soot API Performance Bottleneck

[nathan gulley <ngulley@juno.com>]

Hello all,

I am trying to use the Soot 1.2.2 API to load and instrument classes on
the fly. However,  I have been constrained from using it in a practical
context by a Soot API performance bottleneck. Running on a 750 Mhz CPU
with 56 MB RAM, it takes over 5 seconds to "create and set the scene":

            Scene scene = Scene.v();
           
scene.setSootClassPath(System.getProperty("java.class.path"));
            scene.loadClassAndSupport("java.lang.Object");
            scene.loadClassAndSupport("test.Logger");
            scene.loadClassAndSupport("com.rtscinc.util.Assertion");
  

Also, it takes over 11 seconds to create an instance of a "SootClass":

 SootClass sClass = scene.loadClassAndSupport("com.acme.Foo"); 


I would like to know if anyone else has encountered this performance
bottleneck as well as any advice on how to overcome it. 

Nathan
