TLA+ is used to model concurrent and distributed system protocols helping to eliminate high level design and semantic bugs. I’d expect this class of bugs to also surface in microservices systems.

This can be a problem in a lot of content management systems such as WordPress or Magento, because theme developers tend to scale images down in responsive themes using CSS. An easy way to compress images is with our image processing service that happens to also be fully integrated into our existing network.

The truth is that the two tools were fairly distinct until PSI was updated in 2018 to use Lighthouse reporting. Chrome DevTools includes a separate “Performance” tab where the testing environment’s CPU and network connection can be artificially throttled to mirror a specific testing condition, such as slow internet speeds.

Next, we’ll look at how to set up servers and clients (that’s the hard part unless you’re using a content delivery network (CDN)). Using just a few (but still more than one), however, could nicely balance congestion growth with better performance, especially on high-speed networks. This is true, but only to a relatively limited extent.

Thanks to progress in networks and browsers (but not devices), a more generous global budget cap has emerged for sites constructed the "modern" way: ~100KiB of HTML/CSS/fonts and ~300-350KiB of JS (compressed) is the new rule-of-thumb limit for at least the next year or two.
