  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.

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’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-company-switched-to-hyped-technology/ 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.
