Go's default concurrency performance is surprisingly hard for Rust to match

So this week I had a thought about how Rust would perform against Golang in concurrency and CSP.

For this benchmark, I used Claude Code to write the entire benchmark suite.

Turns out that default Tokio and its channels lag considerably behind Golang in many cases.

Default Tokio vs Crossbeam vs Go

Crossbeam is included mainly as a channel baseline. It uses OS threads rather than Tokio’s async runtime, so this isn’t an apples-to-apples runtime comparison. I wanted to see how much of the difference was coming from the channel implementation itself.

I had Kubernetes installed on my homeserver. I still chose Docker Compose.

Not because Kubernetes couldn’t run it. It absolutely could. I chose Compose because the entire point of this server was to make my life easier, and I know exactly where “I should probably just use Kubernetes” ends for me.

Let me back up.

I always wanted to have a server of my own. The list of what I needed was pretty basic:
