Netfrastructure's model is an in-memory database using the disk as a
back fill. Indexes and blobs live on disk/page cache, indexes because
nothing is gained, and blobs, well, because they're blobs.

The page generation engine, for which conventional databases have no
analog, is all memory.

Running high volume web sites, the only I/O tends to be logging and
whacks at the word search index.
