The pref.data file isn't any use to me without your full build tree, so the best way to use it is to then run 'perf report -g' and investigate where the highest CPU users are, and what calls them. (it is curses-based tool). The 100% busy CPU is because the LDAP server is single-threaded, so that isn't really unexpected. I hope this helps you make some more progress chasing this down.
