Portage *does not* look at CFLAGS in determining what to rebuild (even with -uDN) - portage only looks at USE flags and dependency upgrades/versions. Mike is correct in saying that, for packages to be recompiled with the new CFLAGS, he would have to recompile that package directly. emerge -e world is a good way to do this.\ -James > > If you need a speed boost in Firefox, there is some additional > tweaking that can be done.

Removing Pango will almost definitely increase the render/scroll speed of Firefox. However, from the symptoms that Mike is describing (system-wide momentary pauses, after which the system resumes normal responsiveness) sounds much more like a kernel-level issue - either I/O speed issues (check to make sure your hard drive is running at full speed and you have native controller supported compiled in to your kernel - also, what is your I/O scheduler set to by default?) or the Scheduler (process scheduler). What version of which kernel are you running? What does your .config look like? I had similar issues with momentarily frozen responsiveness on my laptop, until I upgraded to 2.6.23.x, which has the new CFS scheduler in it - seems to help responsiveness quite a bit.
