Thank you guys. You refilled me with sufficient amount of arguments to prepare answers for myself.
I do not know if I will continue with the benchmark, but it would be nice to shorten the performance gap a little and collect adequate measures, in addition to other aspects you mentioned.
We also played for some time with VertX but after a while it became obvious it’s a somewhat obscure, although very very fast, technology with a very little user base, at least they are not visible.
I’ve tried their approach to web pages generation but it is like light years from the experience that you can have with say ASP NET Core. It is faster, definitely, but not when it comes to development, when it comes to development it felt like this was just a student’s project that was enough for his barber’s pages.
There are just six guys at Red Hat working actively on this project and the rest lays on the community and I don’t think it’s working out that well. I’m just working on their https://start.vertx.io/ page it could have been done in days, we are “working” on it for months because of their workload.
You said some lag in JVM !!!
Using which JVM GC ?
I use ZGC for really huge ram but not appear any lag !!!
Almost five years have passed, I can’t find the Ruby-Vert.x-based repo to repeat the test.
But the main point in our case was not about JVM vs. ErlangVM. It was about the easy transition of Ruby developers to some faster tech stack. Since with Vert.x, you just write Ruby, and Elixir has ruby-ish syntax.
We found out that in both cases, Ruby developers have to adjust to a new mindset. The syntax is secondary.
If one wants a raw performance, they should go entirely with C++ or Rust (according to Round 20 of TechEmpower benchmark, which is latest for the moment). Or drop some NIFs into critical parts of their app.
We have Ruby, Elixir, and Java (Spring, I believe) projects in our company. Clients come with some preset, and we never had to convince them to change the stack because of inability to scale.
If we start a new project, the choice is based on the available and planned resources.
I still feel that Elixir allows me to design better solutions in terms of architecture.
