Raspberry Pi and armhf benchmarks?

Hi, reading from wiki [1] I found out about armhf - "hard float" optimization that some raspberry Pi distros have but most dont.

There are some info online that "hard float" optimization can speed up floating point operatins upto 300%, but there are currently no benchmarks to prove these claims.

Has anybody tested this claim? Are there any benchmarks? How to do cross distro benchmars on raspberry Pi ?
