When new, shiny things appear, architects often struggle to determine whether this is merely the latest fad or a genuine future direction. Microservices are evolving from fad to trend.

A Not-Called Function Can Cause a 5X Slowdown

Randon ASCII

Tim Kadlec

By now, I have to be on record at least a few thousand times in saying that WebPageTest.org is an absurdly valuable tool. Pat gave the performance community an incredible gift by building it and making it available to the broader community for free. I spend a lot of time in WebPageTest. A lot of time. A while back, I made myself a little Alfred (like Spotlight but significantly more powerful and useful) workflow to make it easy for me to fire off a test quickly.
