[Fedora-directory-users] CPU utilization

We were seeing similar CPU utilization recently. The problem turned out to 
be a lack of indexes. The web app for looking up people had changed 
recently and was doing substring matches on two attributes that were not 
indexed at all, much less for substrings.  Once I created the indexes, CPU 
utilization dropped from 99% to under 2%. You might check your access logs 
to see what sorts of searches are being done and confirm that you have 
indexes in place to speed things up.
