I’m sure there is good stuff there but superficially it is oh soo close to this: https://saagarjha.com/blog/2020/05/10/why-we-at-famous-compa...

Oh yeah, the headline and some of the article text is like that!

There is some good stuff like you said.

Brief summary: after attempting many optimizations with Go, they attempted a rewrite in Rust—since they had experience using it for some of their other essential services—which resulted in a performance boost along with avoiding the (memory) inefficiency Go incurred: forced garbage collection that affected their cache and resulted in spiked CPU usage and response times.

If anyone happens to work at Discord, keep up the first-class work. I have a few quibbles with your service (please give me a way to let people create channels, not delete them!) but overall Discord has been an A+ competitor to slack.

I hadn't noticed that this was a dupe, apologies.

I was reading through another HN submission from qvault[0] and found this linked article to be a nice read. So, I checked it using Algolia's search[1] first and then decided to post it.

Anyways, good read!

Not to worry! Perhaps you checked by URL rather than title (edit: ah yes, I see that from your HN search link). The two URLs are significantly different in this case.

I usually search by both url and title just to be sure. When searching by title I usually distill the search down to a minimum, - e.g. "Discord Rust" - basically a spanning set for all the articles that might fit. Then if necessary, I use "points>N" or "comments>N" to narrow it down.

You’re doing God’s work. Thanks for all the effort you put in, and still making time to tell us about how you do it.
