Re: [g-a-devel] At-spi2-atk performance tests

Hi again!

This is the new results (using Orca) without bugs. :P
Note: once more, in the sysprof "acc. enable + orca" case, I've added the Orca cpu time in both cases.
As you can see, results are a bit peculiar. But, now, I'm sure it's not a bug. I've repeated the tests 3 times with the same results. 

- On the sysprof case:

    - Nautilus: we have no changes or, even, a minimum deterioration.
- Rhythmbox: we have a little improvement, but It's curious that in the "acc. enable" case, the result doesn't be higher. 

- On the valgrind case:
- Nautilus: it's a very representative case, but "after" and "master" cases continue growing linearly. - Rhythmbox: it's similar to the previous case, but the "acc. enable + orca" case results are a bit singular. I don't know what's the problem, but I think it could be related with Orca. Also, the "after" case it's a bit singular. The consumption is practicaly the same on the 3 subcases. I don't understand why.
That's all today. I'm just working on the "script" version. It's possible I finish it between today and tomorrow. 

Best regards,

                        Alejo.

- Explanation:

           
            

The previous data are organized by tool/app/commit-time/accessibility.

           
            

Sysprof data are expressed in percentage of CPU time.

           

  Rows:

           

    Results before the commit.

           

    Results after the commit.

           

    Results over the master branch.

           

    Differences between the previous rows.

           

  Columns:

           

    Results wit accessibility disable.

           

    Results wit accessibility enable.

           

    Results wit accessibility enable and Orca running (note: in this case, results are the sum of app and orca).

           

    Differences between the previous columns.

           
            

Valgrind data are expressed in bytes of consumed memory.

           

  Rows:

           

  The same as sysprof.

           

  Colums:

           

    Results wit accessibility disable.

           

    Results wit accessibility enable.

           

    Results wit accessibility enable and Orca running.

           

    Differences between the previous columns.

           

    The same, but expressed in percentage (like 2nd - 1st / 1st).
