For the record, PageSpeed caches optimized results server-side, to avoid delaying responses to users. Initial requests for a website are served unoptimized, while the optimization occurs in the background, server-side, and saved in cache. Subsequent requests are served optimized quickly. There is an increase in response time for HTML when running PageSpeed, due to parsing overhead, but on modern processors with reasonable size HTML pages, it is generally just a few milliseconds.
