Bug#521727: linux-image-2.6-686: desktop app are not responsive (kmail, firefox, OO)
Package: linux-image-2.6-686
Version: 2.6.26+17
Severity: important
Standard debian kernel lack responsiveness for a desktop usage.
- Kmail is unusable while checking new mails (in big dimap maildir)
- OOcalc cannot scroll smoothly a page with many graphics from a big
calc sheet
- Firefox is soooooo sloooowwwww
This can be easyly fixed by changing 2 settings in kernels
CONFIG_PREEMPT_VOLUNTARY=y
CONFIG_HZ_1000=y
CONFIG_HZ=1000
and for firefox, adding the one liner regression fix ofr 2.6.26:

Maybe debian need a 2.6-desktop kernel, and not only server tastes.
With these 3 config change + patch, my desktop is usable again
