shlomif[fcs]:~$ perl -E 'say ((73.6936609745026-72.7685720920563)/72.7685720920563*100)' 1.27127529900685 Kudos for the exact calculation. And yes, I agree that most people won't bother with this, but still the system running the vanilla kernel otherwise felt faster and snappier, and some people may wish to go to the extra trouble for that. (Without caring too much about the 1.27% speed increase in Freecell Solver's speed.). I don't know how much, and I'm possibly quite above the average computer user, but this option should still be relevant. I agree with you that most people should not bother with this and just use the packages that their distribution provides. All that put aside, as a software developer, I don't find 1% speed increases negligible, because when put together, they add up to significant savings. See what I wrote about it here: http://en.wikibooks.org/wiki/Optimizing_Code_for_Speed (Search for «"Small"» (with the double-quotes, but without the angle quotes).

I think this joke would be funnier if it said "and I change it every month." instead of "but I change it every month.".
