Sorry, I have to say this is a poor and unpersuasive case for the architecture. Performance increases are everything, yet unless I’m missing it there is no way

Sorry, I have to say this is a poor and unpersuasive case for the architecture. Performance increases are everything, yet unless I’m missing it there is no way to know what the improvements are. For example, data on the chart here http://www.betrfs.org/faq.html http://www.betrfs.org/faq.html, is enough information provided to reproduce the results including hardware and configuration? If not, the results are utterly meaningless. Forward looking, it would strain credibility if you hadn’t tried to get a sense of the real world gains on Intel XPoint storage. I would speculate it will not be many years before there are no new green field deployments of storage that spins around in a circle.

First off, why would you use a research file system on enterprise hardware? Secondly, if you read just a little bit further you see that they are testing using spinning rust (HDD). Since they mention threads, I would hope that they are testing using something that supports hardware parallelism. So probably some relatively decent modern hardware. Mind you this is all speculation, and conclusions you could draw by reading the FAQ carefully.

  If you describe results of an experiment, you need to provide the detail or pointer to how to reproduce it. Benchmarking on enterprise hardware is completely relevant because that is the technology that is going to become dominant over the next few years so if performance gains do not show up on that type of technology they may not significant. In some cases enterprise hardware is much different from what would be used in other scenarios, or on a massive scale, similar to how Facebook doesn’t go down and buy enterprise servers to run their data center. However in this case, the new generation of memory/storage hybrid will not be that different whether it’s in your laptop or in a server, Size features and scalability withstanding of course. If I read an FAQ question that doesn’t have an asterisk or a pointer to the full information, it’s not my responsibility as the reader to go hunting around for details. This is the job of the author of the paper or website. You don’t get to brag without putting a
