Thanks for this data. It looks like I may have an audio bottleneck. opreport -t3 shows 31.5811 no-vmlinux 14.4701 libswfdec-0.9.so.3.0.0 8.3210 libasound_module_rate_speexrate.so 6.0088 libc-2.8.90.so 4.7060 libpixman-1.so.0.12.0 3.6615 python2.5 3.2831 libcairo.so.2.10800.0 If I just look at the libraries I see the top libswfdec routines are all audio related: 14.1497 libswfdec-0.9.so.3.0.0 swfdec_sound_buffer_get_n_samples 2.1666 libswfdec-0.9.so.3.0.0 swfdec_audio_format_get_channels 1.9369 libswfdec-0.9.so.3.0.0 swfdec_audio_format_new 1.7904 libswfdec-0.9.so.3.0.0 swfdec_audio_flv_render 1.3205 libswfdec-0.9.so.3.0.0 __i686.get_pc_thunk.bx 1.2073 libswfdec-0.9.so.3.0.0 swfdec_audio_format_get_granularity I could try using the PulseAudio backend instead of ALSA. > You can try to improve your performance by using latest stable version of > cairo and pixman OK, I am currently using the latest Ubuntu versions which are a bit behind latest stable. I will see if this makes a difference. Package Ibex Latest xorg-xserver 1.5.2 1.5.3 cairo 1.8.0 1.8.4 pixman 0.12 0.13.2 > play a bit with your X video driver config ie. exa vs xaa. I did not see libexa.so in my oprofile output although it is installed, so I will make sure this is enabled.
