The Windows registry is organized into a vaguely tree-like recursive structure, demand-paged and cached in RAM.
The Linux filesystem is organized into a vaguely tree-like recursive structure, demand-paged and cached in RAM.
Performance-wise there isn't much difference unless you're using a braindead filesystem. The frequently accessed and recently modified stuff will be in RAM, and everything else won't.
It would be better to tweak the demand-paging of the executables. Reading 4K at a time according to quasi-random execution paths is stupid when it's faster to read 500K of data from disk than it is to read 4K, seek 492K ahead, and read 4K.
