When talking to Walter about optimizations on modern hardware, bearophile provided the folowing link to a manual about hardware optimization:

http://www.agner.org/optimize/

The author of the manual also provides a free library called "asmlib":

http://www.agner.org/optimize/

This library provides optimized routines for things like memcpy and strcmp. He provides benchmarks that show that they perform better than the Microsoft, GNU, Intel equivalents when running on modern CPU's.  Should this library be considered for use by Phobos/Tango?

The second link should read:

http://www.agner.org/optimize/asmlib.zip

It's GPLed. Also the random number generators can't be used in gambling applications (!) So unsuitable for a standard library. Can use the ideas, though <g>.
