I have noticed that okular recently started breaking into a sweat when it
renders pdf files. Even a four page document with a bit of colour and
graphics seems to push the cpu:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
16387 michael 23 3 466m 52m 30m S 102 1.3 0:36.88 /usr/bin/okular
In case someone can interpret the content of the file:

=====================================================
Once rendered, the CPU goes down to normal levels. The problem does not seem
to occur when the pdf is just text, i.e. no photographs, or complex graphics
in it.
Other than the various top apps, perhaps you can try lsof?
