Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What happens if you put HTTP server inside Postgres?
In the past weeks, I've taken the task of adding an embedded HTTP server to Omnigres. Since Omnigres is implemented in C , it was only natural for me to choose libh2o to implement the functionality of an HTTP server. It did help that H2O is known for its good performance characteristics.

35M Hot Dogs: Benchmarking Caddy vs. Nginx
h2o [1] was excellent when I tried it for TLS termination. And it got http/2 priorities right. It's a shame they don't make regular releases.

C++ (or C, I guess) application server that's QUIC/HTTP3 ready?
libh2o is probably your friend https://github.com/h2o/h2o
- H2O - the optimized HTTP/1, HTTP/2, HTTP/3 server

Damn callbacks
Also make sure you hydrate your server properly as well.

Nginx is now the most popular web server, overtaking Apache
How about H2O? It's supposed to be significantly faster than Nginx: https://h2o.examp1e.net/

Any Load Shedding packages out there?
Does anyone know if there's a reputable OS load shedding / concurrency limiting package similar to Netflix's concurrency limits Netflix/concurrency-limits (github.com) for NodeJS? I'm migrating some middleware written in Kotlin to NodeJS and wanted to know how folks typically solve this problem.

35M Hot Dogs: Benchmarking Caddy vs. Nginx
Under heavy congestion the goodput (useful throughput) will drop to 0 because client will start timing-out before the server get a chance to respond.
Caddy should use an algorithm similar to : https://github.com/Netflix/concurrency-limits
Basically check what was the best request latency, and decrease concurrency limit until latency stop improving.

FWIW envoy also has an adaptive concurrency experimental plugin that seems similar that I'd also love to hear about any real world experience with:
