Good stuff. The first few paragraphs might lead the
short-attention-spanned to the wrong conclusion, in particular:

"Serving directly from system memory is universally the fastest method
of serving content. Reading files from a disk controller or, even
worse, from a remote network is orders of magnitude slower. Disk
controllers usually involve physical processes, and network access is
limited by your available bandwidth. Memory access on the other hand
can take mere nano-seconds."

But it does go on to detail the issue at hand. I'm torn between
wanting to stick the right solution in people's faces and not assuming
they're idiots, but linking to here is a reasonable compromise.
