Without build optimizations (incremental builds, caching, we will get to those soon) this will eventually become unmanageable as well — think about going through all images in a website: resizing, deleting, and/or creating new files over and over again. Under the hood, it simplifies a lot of the work to the server-side.

A WordPress website comprises many parts, including web servers and their settings, different plugins, and themes. But if you have not optimized your WordPress properly, your WordPress will definitely be slower than your expectations. Several website speed testing tools available could be used for this purpose.

For all HTML responses, I pass a Cache-control: max-age=900, must-revalidate header. This tells the browser to cache the response for 15 minutes ( 900 ⁄ 60 ). After that, it has to revalidate—basically, talk to the server again to make sure the asset is still valid and a newer version isn’t available.

The cache hit was very low (a topic for another day), and whenever the server had to provide a fresh version of the page, it was taking an unacceptably long time more often than not. It added a lot of size to the HTML (anywhere from 50-100kb depending on the page), and we suspected it was a big part of the server delay as well.

Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). This is one of the main reasons why content delivery networks (CDNs) exist: They place servers physically closer to the end user in order to reduce latency, and thus delay, as much as possible.
