I am saying the above with full understanding that there are programmers out there who were educated in C++ circles and are sure that garbage collectors are for inferior languages. That is a shortcoming of their education.

For short running tools and low volume stuff, yes, GC is good.

My practical experience running vibe.d service with GC in production: default GC is a bane. Default should've been @nogc.

I would like to hear your experience with Vibe.d. I would care about performance scaling. I have been genuinely interested in using it for years but I did not dare to jump into it. As opposed to Django.

But my intuition tells me that sooner or later Django backends for small things like what I do will be a resource hog compared to D? True that I can partition, do microservices, etc. but that complicates things. On the positive Python side, there is no compilation step and that helps a lot in many situations.

Is django really that much of a resource hog though? If stuff like Instagram can use it just fine, maybe we're just being overly pessimistic?

Also, a benchmark site : https://www.techempower.com/benchmarks//#section=data-r21&test=composite

Just do ctrl-f and look for vibed and django

For those who want a 1 number summary:

vibe is at 92
django at 137

It can be quite nice, but you can do lots with all the other things. I believe it's quickly becoming a feature where people will be pretty upset that a language lacks it. Lack of algebraic data types is definitely a reason why some people are avoiding D in my experience.
