For most page requests, loading all the PHP files through the  
autoloader is the most expensive operation now. The actual file  
loading can be improved by using a bytecode cache. Even more expensive  
is the class name to file path mapping though, especially the regular  
expressions.
The idea is to store this map directly, i.e. without using Horde_Cache  
for obvious reasons, in a cache. Since users interested in speeding up  
the file loading are using APC or similar anyway, the autoloader  
should use such a bytecode cache for caching the map too, if the  
extension supports arbitrary caching.
