Very well put.
Most of SQLite's disk I/O is actually going to the memory used for the
operating system's disk cache, not directly to the disk. Hence its speed
is not much different when using a disk based database than a memory
based database. I'm still a little surprised that a disk based database
is actually slightly faster than a memory based one, but that just means
that SQLite's memory based page I/O is less optimized than the OS's file
I/O libraries.
