update-apt-xapian-index takes way too much cpu cycles

[dronus]

On smaller computers like netbooks, the update process seems much to costly for me. I am a developer and power user, so I use apt nearly every day. But update-apt-xapian-index seems to burn much more time by excessive cpu usage every time the index gets updated that it is not payd off in everyday timesavings by package name completion or synaptic quick search. Does this need to be so slow? If it needs, it should not be installed by default I think.
The non power user will have an even more unballanced experience. Besides of the Update Manager, that is visible and explains itself, the update-apt-xapian-index process is the only periodly running costly process on my system. For a normal user, a sometimes busy system without apperable reason marks the usual sucking unreliable computer experience well known from other OSes. I think Ubuntu must not copy this behaveiour for that special luxury the apt-xapian-index provides.
