I did the following experiment:
- opened 'top' in a terminal
- opened pd and created new file
...the CPU is mostly idle
- with dsp turned off I tried to add one object (a non-existing [test]
one) and move it around
...when I move the object (the window is already updating slowly, around 2 fps), the
Xorg process raises to about 70% CPU usage and puredata process remains
at 2-5%. The command «ps -A | egrep -i 'pd|puredata'» gives the
17 ? 00:00:13 kswapd0
783 ? 00:00:00 pppd
1045 ? 00:08:51 mpd
26605 pts/4 00:00:01 puredata
26608 pts/4 00:00:00 pd-watchdog
(I was running it with JACK, but running through ALSA gives the same
results with only additional puredata process).
The same situation with Pd-extended (except the process name:).
I will post my Xorg.log as an attachment...
