Do the ones at the top (like Actix Pg for example) provide everything you need to do real development, or are they stripped down? In other words, is this comparing track bikes to cross country bikes?
It’s worth looking at low level HTTP, socket and concurrency management if you want faster performance, but that’s not really a language-exclusive feature at that point. And the more realistic you make the benchmark — the more communication between microservices, for example - the more your application architecture, deployment hardware, kernel and network tuning, and so on can play a role.
I am reminded of http://rachelbythebay.com/w/2020/10/14/lag/ for example, as something really low level you probably don’t need to worry about… until you do. http://rachelbythebay.com/w/2020/05/07/serv/ also. The same is true of most of the performance optimization at the top. Really fast? Yes. Useful? Depends on the rest of your code. Are you writing haproxy? How much does your app really need to do? Read the benchmark source code and get inspired, maybe.
My conclusions for the moment: Switch to Go if low memory usage and high performance is as critical to you as post-1.0 stability. Go is generally stable these days ;-) Otherwise if instability can be tolerated but you want high performance, use one of these newer web server techniques and write a web server in unmanaged C++ that has very minimal functionality with language bindings. Just-js can serve as an example. Heck, the PHP benchmarks show that if you use PHP to write your own HTTP server you can still achieve high performance. That tells me the advantage here goes to web servers that literally “do less” rather than picking a language as faster over another language… especially when most (all?) languages can interface with C or C++ to do the HTTP layer at high performance while writing your code in whatever language you choose…
I wonder if the current actix-core is the rewritten/safer one once a bunch of Rusters wrestled/annoyed the original author into handing it over. If so, it's still near the top.
Techempower classifies each one. Actix is what they call a "platform"
>a platform may include a bare-bones HTTP server implementation with rudimentary request routing and virtually none of the higher-order functionality of frameworks such as form validation, input sanitization, templating, JSON serialization, and database connectivity
Even if you use the top ones in the list, you will have to build abstractions in code to handle software complexities. Those abstractions will reduce performance.
I do wonder, if we could use AI to dynamically remove those abstractions, to the extent possible and transform abstracted, multi-layer code to simple functions / compile targets, improving performance. Sort of like looking at the project, at this instant, and folding all database / processing code into higher performance code that reduces function calls or object instantiations.
Yes they offer everything we need for real development at enterprise scale.
