I absolutely love how every single update since the original nokia PRs, of every major system package (I.E. Nokia PRs, CSSU, and Kernel Power), there's a large chunk of people who notice speed improvements, when the package doesn't in any way change the stuff that effects speed.

Of course, to be fair, it's possible that something speeds up right after a new system-wide update, perhaps because of some deep down workings in some of the closed binary blobs on the N900... but I just don't see that as likely. On the other hand, I'm sure there's been times when I've fallen victim to the same placebo perception effect. *Shrug*

For my part, I don't perceive any increase in speed. But that might be just me being odd, or alternatively, me getting the same placebo effect in reverse from perception. That said usually when code likely to increase performance speed is introduced, people comment on the matter, so lack there-of suggests no such patches.
