Standard disclaimer: Use at your own risk!
Basically disabling the scrolling cache will reduce lagy and chunky scrolling. You won't notice a huge difference unless your scrolling through something your phone usually has a hard time with. Anyone that has Rom Toolbox would understand chunky scrolling on the first page of the app. So if you have the app, test it there. In general, icons will appear instantaneous and everything will run a bit smoother.
So here is what to do...
Use your favorite build.prop editor and add a new line.
Set it's value to 3.
If you really want to make things extremely more responsive then adjust your vm.stat_interval. I do believe the default is 10. If someone could verify it before you change it let me know. Setting the value lower will increase the responsiveness of your phone a very good amount! Start at 8 and slowly work down. There is a chance you will become unstable so use caution. I can say I have set it to 1 (lowest setting) without a single issue.
Do not expect to increase your benchmark with this because it will actually drop a little. This is a perfect example of the whole benchmark debate. Your phone will be flying but quadrant won't show it.
Use the "SCOL" app to adjust vm.stat_interval and save your value. There is no need to reboot and the results of your changes are instantly applied.
Yes. It is most likely going to effect battery life.
