After upgrading to 10.04LTS i noticed that nepomukservices, strigi? and a new thing called virtuoso-t once again was more or less stopping my computer with a combined near 100% CPU load. I am not very surprised by this, as it has kind of been the norm on the last releases (all KDE 4 ones, right?). To get my desktop environment to communicate with the user again at a reasonable efficency, I have had to disable the whole ensemble of services and gizmos as far as is possible from the system settings panel. I could leave it at that.
Only seeing that it is still there, in an LTS release by default (after near complete uselessness in n releases) indicate that someone somewhere must have found it useful - and working at least partly to the intentions, which are quite visionary.
So I wondered, is there anyhow I can tune this beast to perform well on my computer?
I have a toshiba laptop which already have reached the noble age of 3 years old. It has a dual-core processor although it was never one of the really strong ones. Also, my hard-disk is encrypted, and I do believe this may be part of the problem, as hard-disk scanning includes decryption and writing (the database) necessarily adds encryption to the processors to-do list.
The symptoms I experience is frequent (at least once per hour, but I think more often) heavy hits to system performance because all the nepomukservices, virtuoso-t, (and strigi?) with associated encrypt / decrypt surge to close to 100%, which makes my user interface practically stop, until these processes have finished their job (I estimate 5-10 minutes for this each time, but have not done the statistics).
My idea is that if it somehow was possible to limit the intensity of CPU craving by the sum of these associated processes and desprioritize them, and maybe do the scans less frequently, it may be possible to have a useable desktop search and a practically workable computer at the same time.
Does anyone have any success stories I can learn from, along the lines of the ideas I have posted above, or completely different ways that the desktop search gizmos can actually get to work without paralyzing the computer? I am willing to give it one more shot if I can get some leads.

I hope KDE4.5 fixes that (of course by now most of the exams are already over...)
