Elixir and Go both have similar performance (although Elixir tends to use a lot more CPU). Here's a pretty good blog post comparing Go, Node and Elixir: https://stressgrid.com/blog/benchmarking_go_vs_node_vs_elixi...

I hope I'm missing something here because that's an absolutely awful benchmark. Neither Go nor Elixir were stressed enough to start revealing failure symptoms, so Go could still destroy Elixir by 10x for all we know. Then Node was run single-threaded even though the test instances had 8 or 36 vCPUs.

But some people will still walk away thinking that Go and Elixir perform about the same while Node is 4x slower.

Eh. This blog post runs a single node process on a 36-core CPU. I'm not a fan of node but that's hardly a meaningful benchmark
