Hi, I'm trying to get to the root cause of some performance issues using pygobject. Running a video player using GStreamer and Clutter directly takes about 8% CPU, whereas running the same functionality via gobject-introspection and pygobject from Python takes more than 50% CPU! Profiling the system load with sysprof unfortunately does not help as in the Python case most of the load is consumed "in kernel" where no further information can be retrieved from. Profiling the "native" application does not show any "in kernel" portion of the system load. Currently I'm using pygobject 2.28.0. Any idea appreciated.
