Comment 3 for bug 655831

Yes, I think also that bug 131094 is responsible for this.

NoOp, note that when update-apt-xapian-index is run automatically, it is launched with nice and ionice to be less intrusive, so "benchmarking" with calling it directly is not correct. And high CPU usage is perfectly normal if it runs alone.

What I find abnormal is the accumulated CPU usage, it seems unnecessary to do so much computation to update an index. But that can be more poor design than a bug. Naturally, most developers have very powerful machines, so these things often go unnoticed.
