SEPTEMBER 6, 2022
I have long held very strong opinions about the Critical CSS pattern. In theory, in a perfect world, with all things being equal, it’s demonstrably a Good Idea™. However, in practice, in the real world, it often falls short as a fragile and expensive technique to implement, which seldom provides the benefits that many developers expect. Let’s look at why.

You may remember Dataflow from the post we wrote last year titled Data pipeline asset management with Dataflow. That article was a deep dive into one of the more technical aspects of Dataflow and didn’t properly introduce this tool in the first place.

When I worked at Google, fleet-wide profiling revealed that 25-35% of all CPU time was spent just moving bytes around: memcpy, strcmp, copying between user and kernel buffers in network and disk I/O, hidden copy-on-write in soft page faults, checksumming, compressing, decrypting, assembling/disassembling packets and HTML pages, etc. If data movement were faster, more work could be done on the same processors.

We described the tools and techniques we use to gain insight within each domain. There is, however, a class of problems that requires an even stronger level of magnification going deeper down the stack to introspect CPU microarchitecture.

Kubernetes is used by many organizations to build, deploy, and manage large-scale distributed applications. However, the overwhelming advantage of running applications on Kubernetes comes at a cost. Progressive rollouts, rollbacks, storage orchestration, bin packing, self-healing, cost efficiency, and access to the Cloud Native Computing Foundation (CNCF) ecosystem carry heavy observability challenges.

For the longest time, hosting static files on CDNs was the de facto standard for performance tuning website pages.

Over the years, the whole idea of software testing has evolved.
