2017 AWS Latency Speed 
Brendan Gregg

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? Aftermath I provided details to AWS and Canonical, and then moved onto the other performance issues as part of the migration.

It's an exciting time for developments in computer performance, not just for the BPF technology (which I often [write about]) but also for processors with 3D stacking and cloud vendor CPUs (e.g., Ford, et al., “TCP on Upcoming Sapphire Rapids CPUs,” [link] Oct 2020 - [Liu 20] Linda Liu, “Samsung QVO vs EVO vs PRO: What’s the Difference?

Today, I am happy to announce our plans to open a new AWS Region in Italy! The AWS Europe (Milan) Region is the 25th AWS Region that we've announced globally. It's the sixth AWS Region in Europe, joining existing regions in France, Germany, Ireland, the UK, and the new Region that we recently announced in Sweden.

Today, I am very excited to announce our plans to open a new AWS Region in France! Based in the Paris area, the region will provide even lower latency and will allow users who want to store their content in datacenters in France to easily do so. The new region in France will be ready for customers to use in 2017.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP
