[Soot-list] debug statements impact performance

[Attila Bartha]

Hi

 

I just bumped into an example of a typical performance killer:

 

In class soot.dava.DavaBody: 

 

      DavaBody(Body body) {

            this(body.getMethod());

            debug("DavaBody","creating DavaBody
for"+body.getMethod().toString());

            Dava.v().log("\nstart method " + body.getMethod().toString());

 

The invocations of debug() and log() are unconditional. The accumulated
computation time for calculating the arguments can be significant. The
condition within the debug() method does not solve this problem. It could be
a quite a performance improvement to do a cleanup by adding conditions like

 

if (DEBUG) debug(.)

 

Cheers

 

Attila
