</div>That won't save power for an application that runs forever though, which<br>
is what Evan wants (running a BOINC client).<br>

Seems like a good use-case to me; any (almost) perpetual background-task<br>
should not scale up the CPU frequency. How to implement that behaviour<br>
is up to the linux devs though... ;) <br></blockquote><div><br>It is already implemented in the form of the ignore_nice_load setting. This site [1] explains it well.<br><br>The bug report [2] is because in Jaunty, this setting is ignored, and not honoured.<br>
