I found this data a bit difficult to read. A handy graph tool can be
found here:
http://code.google.com/p/jrfonseca/wiki/Gprof2Dot
I used:
$ python gprof2dot.py gprof.out-100000-sqlite | dot -Tpng -o sqlite.png
The graph is quite large (and takes about 650 Mbyte of RAM to make!) but
it is easier for me to understand than the text output. Now that I know
what stuff means I can possibly use the text directly though. :)
