Back in 2017 the engineering team at Facebook had a problem. While ultimately this new system should be able to take advantage of the latest advances in consensus for improved performance, that’s not realistic given a 6-9 month in-production target. replacing Paxos with Raft), or they could be shims over external storage systems.

TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB. To update our global baseline from 2017, we want to update our priors on a few dimensions: The evolved device landscape. Advances in browser content processing. The Moto G4 , for example.

The new AWS Africa (Cape Town) Region will have three Availability Zones and provide lower latency to end users across Sub-Saharan Africa. In 2017, we brought the Amazon Global Network to Africa, through AWS Direct Connect. With the AWS based system, Exatype can do this at a fraction of the cost.

Linux load averages are "system load averages" that show the running thread (task) demand on the system as an average number of running plus waiting threads. This measures demand, which can be greater than what the system is currently processing. then your system is idle. - cat /proc/loadavg. 42/3411 43603.

With these requirements in mind, and a willingness to question the status quo, a small group of distributed systems experts came together and designed a horizontally scalable distributed database that would scale out for both reads and writes to meet the long-term needs of our business. This was the genesis of the Amazon Dynamo database.

After 20 years of neck-in-neck competition, often starting from common code lineages, there just isn't that much left to wring out of the system.

So, if we created an overview of all the things we have to keep in mind when improving performance — from the very start of the process until the final release of the website — what would that list look like?
