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?

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's an important vendor-neutral space to share the latest in technology.

During this time we did do plenty of hard work, rolling out new technologies and major microservice versions, and fixed many problems big and small. The proactive projects usually take weeks or months, and are where I'm developing a new technology or helping other teams with performance analysis or evaluations.

The talks are up on YouTube , including my own (behind a paywall, but the slides are freely available [1] ): The talk, like this post, is an update on network and CPU realities this series has documented since 2017. These are depressingly similar specs to devices I recommended for testing in 2017. 2023 Content Targets #. 4GiB of RAM.

Here's some output from my zfsdist tool, in bcc/BPF, which measures ZFS latency as a histogram on Linux: # zfsdist. Tracing ZFS operation latency. And namespaces, used for Linux containers, are also a relevant technology. Solaris may not survive, but certain technologies and expertise will. Hit Ctrl-C to end. ^C
