Over the last decade I’ve been playing with dozens of servers from multiple providers. These are the steps I’ve been perfecting to get up to speed fast and feel right at home on a new machine. Wrote it down here mostly as a personal reference, but hopefully useful to someone else too.

Fair, but agentic tooling can benefit quite a lot from this

Opencode, ClaudeCode, etc, feel slow. Whatever make them faster is a win :)

I'm not sure about the single-core scenario, but would love to learn if someone else wants to add something

In reality multiple threads for single core doesn't make much sense right?

Thanks. Do you happen to know why hyperthreading should be disabled?

In prod most trading companies do disable it, not sure about generic benchmarks best practices

Codeberg vs selfhosted Gitlab. What do you think?
dalvrosa
·4 mesi fa·discuss
Agreed. For benchmarking I used this <https://github.com/david-alvarez-rosa/CppPlayground/blob/mai...> which relies on GoogleBenchmark and pins producer/consumer threads to dedicated CPU cores

What else could be improved? Would like to learn :)

Maybe using huge pages?

Exactly, that's right
