indirection and perf

This recent post by Phil Windley had a great paragraph in it about indirection and performance.

You know the saying “there’s no Computer Science problem that can’t be solved with a layer of indirection.” In homage to that, our solution is to redirect from a static URL to the timestamped filename. That’s not ideal, but it works. The downside is the other half of that homily: “there’s no performance problem that can’t be solved by eliminating a layer of indirection.” Still, our measurements show that the price we’re paying isn’t too high.

Good stuff. We all know it - he just has an amusing way of saying it.
