You can try to do some profiling.
You would need a build with --enable-symbols and valgrind installed.

Just set:

export VALGRIND=callgrind

Then run LO (It'll be much slower!)

>From a 2nd terminal you can run callgrind_control, which shows you the
profiled programs with PIDs. When the GUI is visible and the document
loaded, just "--dump" the stats and "--kill" the program with
callgrind_control (see --help); probably "--kill" is enough and you
don't need an explicit "--dump".

Easiest way to analyze the output is to load the result
(callgrind.out.<PID>.1) into kcachegrind.
