This is understandable—forgivable, almost—when you consider that TTFB begins to move into back-end territory, but if I was to sum up the problem as succinctly as possible, I’d say: While a good TTFB doesn’t necessarily mean you will have a fast website, a bad TTFB almost certainly guarantees a slow one. But what else is TTFB?
