I created a bad test case by updating the beacon test. I create a grid
with thumbnails from around 320 (!) beacon items incl. a reflection.
Here are the results:
0.09 seconds to create all python objects. This includes getting the
Thumbnail object from beacon and the filename of the thumbnail in the
~/.thumbnails directory. Without beacon it is around 0.06 seconds. No
clutter objects are created.
0.9 seconds (!) to load all thumbnails (256x256 pixel) using
kaa.imlib2. This only uses _Imlib2.open internally so I don't think we
can ever speed this up. Ideas welcome.
Now we switch into the gobject loop for rendering. Note: the second we
lost above is in the main loop so it does not block animations. It
could also be done in a thread to keep both loops alive.
0.7 second (!) to create all clutter actors and render what we
need. Without the reflection it takes 0.6 seconds. I'm sure the huge
problem is transforming the imlib2 image to clutter:
| clutterobj.set_from_rgb_data(imlib2obj.get_raw_data('RGBA'), True,
| imlib2obj.width, imlib2obj.height, 1, 4, 0)
This has to be faster somehow. I know that 320 images are more than we
will ever need, but it is a good test case to find bottlenecks.
