two things:

I am using cfs for a long time now - since shortly after the first patches. 
And everytime a new patch arrived I compared it with an unpatched kernel (at 
the moment 2.6.22.5) and everytime I had the same result:

X is much, much, much and a lot better with cfs. I never had such a snappy X. 
X rules with cfs. It is just great. Under load, without load, it does not 
matter. cfs is better. I am really curios what I did right that you do wrong.

second:
a little bit less text would be great. This was almost TL;DR. You turned a 
simple question about swapsize into a large sermon about your cool box with 
it bazillion of gb ram, its superduper harddisk setup and its amazing 
computing power that makes it survive a 200 load.

Back at school you would have failed the test because of missing the point.

Remember: this is an international list. Less text is almost always much more 
readable. Not everybody enjoys picking the few cherries of relevant 
information out of a sea of words.

Glück Auf
