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. It was a great privilege. That's about 24 hours from now!

A message-oriented implementation requires an efficient messaging backbone that facilitates the exchange of data in a reliable and secure way with the lowest latency possible. The low-level streaming implementations of the mentioned engines require specialized knowledge in order to program new applications.

If you or your company are able to generate a credible worldwide latency estimate in the higher percentiles for next year's update, please get in touch. So what did $650, give or take, buy in late 2017 or early 2018? Front-end developers are cursed to program the Devil's computer. but which blessedly sports 8GB of RAM.

WebGL 2 launched for other platforms on Chrome and Firefox in 2017. Provides support for "unread counts", e.g. for email and chat programs. For heavily latency-sensitive use-cases like WebXR, this is a critical component in delivering a good experience. The underlying graphics capabilities from OpenGL ES 3.0

Back on December 5, 2017, Microsoft announced that they were using AMD EPYC 7551 processors in their storage-optimized Lv2-Series virtual machines. They feature low latency, local NVMe storage that can directly leverage the 128 PCIe 3.0 Since then, Microsoft has changed the naming of this series to Lsv2. Memory (GiB).

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. Was there some other program consuming CPU, like a misbehaving Ubuntu service that wasn't in CentOS? I've shared many posts about superpower observability tools, but often humble hacking is just as effective.
