Eh, I'd assume the comparison isn't flattering. I think the point of this article is to argue you don't need ElasticSearch to implement a competent Full Text Search for most applications. Splitting hairs over a few milliseconds would just distract from that point, when most applications should be prioritizing simplicity and maintainability over such tiny gains in a reasonable dataset.

Might be interesting to try to analyze at exactly what point elasticsearch becomes significantly useful, however. Maybe at the point where it saves a full tenth of a second? Or where it's returning in half the time? Could be an interesting follow up article.
