I'm not sure I should admit to this, but my PC has been running a much less than full speed for some time. I noticed that my dnet client was running a lot slower than it used to. I hadn't noticed other stuff being particularly slow, so didn't give much thought to it.

I did some investigation today and found, via /proc/cpuinfo, that my CPU cores were running at 1GHz instead of 2.4GHz. I did some searching around and posted to a thread on < a href=http://ubuntuforums.org/>Ubuntu Forums that seemed to relate to it. Within minutes I had a response suggesting I add an applet that let you control CPU frequency scaling. That particular applet was for Gnome, but I found KPowersave for KDE. This lets me select various modes, but I just set it to Performance and all is well again.

I guess that I may have been using a little less electricity whilst the CPU was throttled down, but I don't think it's a large part of my usage.

What I wonder is how this came about. My PC was running Ubuntu for some time at full speed, but someting changed to switch it to low speed. I don't have the logs to prove exactly when this happened, so can't relate it to anything I did.

I was thinking of writing a post titled 'Are RSS feeds killing commenting on blogs?'. If you only read sites via their feeds then you probably won't even see the comment part of each page. I've had comments on my site for some time, but get very few. I know that a few friends read the site via the feed. I don't know how many strangers visit. I think that comments are valuable as they make the whole thing interactive. I often click through to posts on feeds to see the comments. So if you want to say something to me about a post please add a comment. It may be useful to others.
