Hardware considerations The first thing we have to consider here is the resources that the underlying host provides to the database. Conclusion Capacity planning is not something you do once a year or more as part of a general exercise. Let’s take a look at each common resource.

If that moment didn’t arrive before credit tightening began, well, time’s up. The credit cycle is certainly making itself felt in a big way.

In some sense it's a confidence-management exercise. In both cases, the OS will task the browser team to heavily prioritise integrations with the latest OS and hardware features at the expense of more broadly useful capabilities — e.g. shipping "notch" CSS and "force touch" events while neglecting Push.

Even though that remediation task was pretty minor — tweaking some low-level hardware settings on each physical server and rebooting — and could have been done quickly enough, there was intense debate on whether it should be done. In practice (and I’ve done this exercise with teams), this spectrum can provide useful insight.

This is an uninspiring fraction of peak performance that would normally suggest significant inefficiencies in either the hardware or software. There was no deep goal — just a desire to see the maximum GFLOPS in action.
