I think this is the problem everbody is dealing with here; load.

These modern systems can handle load easiliy. In the case of modern computers you can achieve greater speed under a greater load. With less load comes less speed.
But what if you're having an older system? Parallel would kill you. The background services, drivers, applications, the GUI all run on the smae thread (with time slicing) as your favorite game. This is slowing things down horribly. So the problem is not speed on these systems, it is just load.
This ammount of load to increase speed in devastating for older computers and they crumble onder it.
So Ubuntu is faster on modern systems where Arch is actually slower.
On older systems Arch is faster than Ubuntu.
Load != Speed
Well, Ubuntu runs smoothly on my Atom netbook (1GB RAM, slow disk, dog-slow CPU, non-existend Intel GPU), so I'm not sure that comparison makes sense.
Arch will likely perform better on low-memory environments (<512MB) but those are not common nowadays. Frankly, it's not as if a modern Arch desktop (gnome, gnome-extras, compiz, openoffice, firefox or their KDE equivalents) is all that different from the Ubuntu desktop in memory usage, disk requirements or compiler optimizations. The main difference is that Ubuntu/Kubuntu ships a different theme, a couple of different apps and a few different patched by default - big effing deal!
(You can compare them on VirtualBox if you don't believe me. The difference is pretty small and Ubuntu boots faster, too.)
This comparison confirms everything I've known for a while. My arch install isn't any faster than my ubuntu install. However, my arch install is consideraby more snappy than my ubuntu install because it's heavily customized to be light and quick.
Windows 7 pwns them both, so there.
Yep. ..I purchase software in the Android Market all the time, I look forward to being able to do the same in the Ubuntu Software Center. I also look forward to having a fixed monthly free software donation rate in an ubuntu one account that gets distributed to my favorite ubuntu packages according to my usage.

Well, Canonical does contribute more than Microsoft, so Ubuntu having 90% marketshare wouldn't be as bad.
Never mind, I've found it. It's well hidden: you have to put UnredirectFullscreen=true under [Compositing] section in ~/.kde/share/config/kwinrc and restart kwin.

i can tell you straight, arch will work better. i know because i've been using it at work for the last 3 years, even though i've been using gentoo since 2004 on my home pc.
package manager is very fast, system is very responsive. and most importanly the package manager doesn't try to outsmart me and run or configure system services for me. that's actually very helpful.
In other words: load the CPU to the max and the speed is the same. Having to timeslice through the usual per time versus timeslicing throught the usual minus backgroudn services that check periodically and other services enables by default that one does not use means more CPU time for you favorite DE/WM and thus: snappier.
