What's the latency difference between a long running process issuing a network call in Java vs rust? This is such a short time that it is completely overshadowed by noise (OS doing something else, what other software is running etc)

As for throughput: you have 1-2 requests going at a time, the next one waiting for the reply. What throughput are we talking about?

That's like speeding to the post office and expecting your letter to get to the recipient faster.

you seem to specifically aim at the current example, but mine wasn't

Anyways, consider how higher memory usage can affect the systems performance dramatically once the system needs to start swapping memory to disk signficantly

If you cannot write a simple Java agent without consuming so much RAM that your system is swapping then that really says more about the developer than anything.

Java is used in plenty of embedded systems and other memory constrained environments. Yes, it’s not going to perform well compared with Rust, but that doesn’t mean it’s an Electron-equivalent bloated clusterfuck of an ecosystem that’s going to eat all your system resources.

> so much

1) the agent is probably not the only thing running on the system, so more is just worse generally

2) I am fine if a developer needs Rust or similar to write a resource efficient app. I wonder what the developer could achieve when he put the optimization effort into the Rust app instead.

[hnlmorg]

My point is that Java isn’t going to be the application that sends your machine into swap hell.

People are so narrow minded about programming on this forum. They talk as if only Rust fills the void between unsafe C and node.js behemoths. But the reality is there are a plethora of other good languages out there too.

I can't put Java into good languages category at least for how it allows null to be everywhere.

Of course, what would be a point of talking about an overly specific statement that has no relevance here?

I mean, the post office is not a magic box. Actual people will take your letter somewhere, sometimes batching sends. So running to the post office might actually get your letter in an earlier batch, same as ordering on amazon or your online supermarket in the morning or in the evening might change the delivery time.

Pedantic, I know, but interesting example.
