Hi All,

I typically develop on my windows laptop, and then shift the code over  
to more powerful ubuntu desktop when I need better performance.

So, I compiled from svn on my ubuntu (13.04) with debug too (though  
I'm not using the sumoD, just sumo) expecting things to be quicker.  
I'm using traci4j, so maybe the issue is in the java code there, but  
then I'd expect same performance on windows.

I wondered if anyone has seen similar issues, or might have an idea  
where the issue comes from?

As an example, checking timings on how long it takes to run 3 commands  
(get position, get angle, and get ID), on my laptop everything is quick:

      [java] vehicle.queryReadPosition took 1 ms
      [java] vehicle.queryReadAngle took 1 ms
      [java] vehicle.getID took 0 ms

On ubuntu:

      [java] vehicle.queryReadPosition took 39 ms
      [java] vehicle.queryReadAngle took 39 ms
      [java] vehicle.getID took 0 ms

The problem is, with > 10 vehicles, this means it takes more than 0.5s  
to gather all the vehicle data and publish it to middleware, which is  
the sim step I'm using.

Seems something specific in the position and angle?

Thanks

Vincent
