Phoronix: Raspberry Pi's Raspbian Improves Its Performance
The Debian-based "Raspbian" Linux distribution for the Rasperry Pi ARM development board is now a heck of a lot faster thanks to recent software improvements...
The Raspi is ARMv6.

Maybe with the RaspberryPi we will witness the game console effect? When every device is (almost) exactly the same as every other a lot of optimizations can be done for that particular device.
As Kamikaze said, Raspberry Pi is ARMv6. Debian has two arm versions... one with ISA v4 and software float, and another that is ISA v7 with hardware float. So Raspberry Pi has to run a more obsolete isa and with softfp when using normal debian. Raspbian is mainly a debian compiled with ISA v6 and hardware floating point... those are mainly the reasons of the performance incrase.
Actually debian has 3 ARM versions - arm, armhf, and armel. RPi I believe is armel, and most other boards are armhf.

Anyways, there's a reason why devs don't micro-optimize their software for a single platform. Even though Pi might be the most popular ARMv6 device out there, optimizations for it COULD negatively affect other platforms, even non-ARM platforms.
Raspbian is a custom armhf variant, actually. Debian's armhf targets ARMv7, Raspbian targets ARMv6.
