One of the big topics at the OpenStack conference was how to prepare and implement a successful transition to 5G. Unfortunately, this means that the age-old Telco bugbears will rear their ugly heads again, including latency. 5G, as a fundamental requirement, mandates a 1 millisecond latency from the datasource to its destination.

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()? I happened to be speaking at a technical confering while still debugging this, and mentioned what I was working on to a processor engineer.

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. Or even on a plane. It was a great privilege.

High-speed networks through 5G may represent the next generation of cord cutting. I don’t need more bandwidth for video conferences or movies, but I would like to be able to download operating system updates and other large items in seconds rather than minutes. Reliability will be an even bigger problem than latency.

The area he was in was served by satellite internet access, and experienced significant latency (a floor of 506 milliseconds) and packet loss (between 50-80% was typical). A local caching server, meant to speed up commonly-requested sites and reduce bandwidth usage, is a “man in the middle”.

Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). Hit Ctrl-C to end. ^C

A Primer on Speed. Discussing performance and “speed” can quickly get complex, because many underlying aspects contribute to a web-page loading “slowly”. Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Congestion Control.
