Using OProfile and GProf2Dot I finally made a callgraph for the first 5 seocnds of a Pidgin startup with a simple Yahoo Messenger Account configured(No I’m not a YIM supporter, this was just the account I used for testing, all my other accounts are to busy to log in/off every 10 seconds(my friends would all get annoyed ;-) ) This graph shows directly that time is spend in calling do_lookup_x in ld-2.7.so whichs source is in most cases dlopen_doit.
