Crystal is incredibly memory efficient, why is this not spoken about more? Or pushed more in the ‘marketing’? Memory is the expensive part of the compute process in the cloud pricing structure. I’ve seen Crystal comparisons where a Node process is 200MB+ & Kemal or Crystal was around 6MB and that’…

I’m not sure if Crystal is particularly memory efficient. Sure, Crystal programs certainly use way less memory than other popular alternatives as you mentioned. But I think ther is some bias. When you consider a simple webapp bloating 200mb memory as acceptable, any significantly smaller memory con…

@straight-shoota I swear, if there is such a thing as genetic predisposition for diplomacy, you have that. I feel the need to translate that to plain language: NodeJS is an incredible resource hog (not just memory, also disk space, performance etc.). Comparing Crystal to that is like comparing a T…

@straight-shoota , since someone discuss on this, i have one more question. i read done all our document, references, but, none of them mention GC, sure i know we are use bdwgc, but, i guess someone still want to know how it works.(not need too detail, but, understood a little is better), and mo…

It’s not just the node example the benchmarks against Julia also showed a huge memory difference. Think in general Crystal is as fast as C & as light as air.

Here’s a previous discussion on Crystal’s memory efficiency. [image] Kudos to Crystal! News The last couple of days I took some time to recompile some code (my segmented parallel threaded Twin Primes sieve) in the newly updated versions of Crystal (1.2.2), Rust (1.57), an…

You’re correct, we’re missing documentation in this regard. Quite frankly, I think it’s very hard to come up with something meaningful and succinct on the topic: most users are fine knowing someone will collect their trash, and advanced users needs more than just the basics. So far, bdwgc’s document…

I think that partially the reason is also the std-lib and ecosystem design. Is not something of the language. Using IO as much as possible, encoding/decoding without needing the whole document in memory, avoiding short living heap allocations; are all things that contribute to the low memory footpri…
