The IBM system had 24xHGST N200 SSD, 830 000 random read, 200 000 random write. that is 24 * 200 000 IOPS=4.8Million random writes.
The Matrix system had 64x1.2TB Micron 9100 SSDs. 750 000 random read, 300 0000 random writes. 64 * 300 000=19.2 Million IOPS
Ok so you have benchmarked hardware with 4.8 Million write ops vs 19.2 Million write ops.

One of the nice aspects of D is that it interfaces with C++ really nicely. I'm not overly familiar with how Rust handles this, as the last time I tried to glue together Rust and C++ was more than a year ago, and the tooling was in evolution. From Go / CGo, it can be pretty scary to interface with native C++ code, and it requires lots of annoying boilerplate.
I've written wrappers for C++ libraries to work with D and it's _very_ easy. To work with C++ classes in D, I created factory methods that created/destroyed them with C ABI and used/disposed them respectively. Working with C is even more easier. There is no FFI, etc. Just use Dstep[1] and get going. Or use dpp[2]. [1] https://github.com/jacob-carlborg/dstep [2] https://github.com/atilaneves/dpp
It's now finally pretty much all in D, and I've been piece by piece refactoring it into more idiomatic D.

Here's the thing though: They wrote a new compiler and a new standard library to make the language work for them. How exactly is that good publicity for D? D itself looked and still looks very interesting to me, as it can be very performant, without having insanely ugly syntax such as c++ or rust (inb4 rUsT iS VeRy ReADaBlE).

I would have liked to hear more about what exactly made D so great -- reading through it it's kind of vague. He mentions generics and finally getting LLVM support working as a target, and being able to use D at a high and low-level but I don't see anything here that's groundbreaking. Could someone who uses D Hate to be that guy, but if you could compare it with rust that would be double A++ good... I know the targets…
D is a work of love by WalterBright and the community. I like to think of D as a true successor to C++ when people compare Go to a C++ alternative. It is between Rust and Go but it doesnt do away with Object Oriented programming or the many paradigmns that exist for different programming approaches. I usually tell people if you can grasp C, C++, C# or Java you are going to understand plenty of Go. Rust has a larger l…

Is this true? Mind speaking on which types of projects it was mostly used?
Congrats for Weka.IO. They managed to pull it through after the CEO visited the DConf and asked for help. D is a brilliant language. I got drawn into D by this article[1]. I've used D to replace some of the test tools where Java/Python were used. GC is a friend in such cases. I could've written them in C++ as well, but Phobos wins over STL hands down! Initially the "solution" test application for one of our REST serv…

My experience, which of course is anecdotal, is that the advantage is it's easy to change the algorithms and data structures. I've maintained C and C++ code bases for decades, and I've found that the first algorithm I tried has stayed there in the code. It gets tweaked, optimized, refactored, but it's the same algorithm and data structure. With D, when I developed the Warp preprocessor, https://github.com/facebookarc…
Yes, this is a great feature. Rust also does this, and I attribute substantial portion of ease of refactoring Rust to this feature.

D feels much more like a 'sane' C successor, dropped from a parallel dimension where C++ could evolve without caring much about breaking its legacy code running the world. It has a few warts, some D v1 leftovers, but overall feels much more coherent than modern C++; even as the latter has grown much closer to D by piling more on top of its templating system. What I personally found the stand out feature of D to be, i…
There was a C successor that's been in progress lately, saw it on HN a few months back, I forget the name of it.
EDIT: Was thinking of Zig
