Production Tuning

Problem: Your API needs to handle extreme load (10k+ requests per second).

Solution

1. Release Profile

Ensure Cargo.toml has optimal settings:

[profile.release]
lto = "fat"
codegen-units = 1
panic = "abort"
strip = true

2. Runtime Config

Configure the Tokio runtime for high throughput in main.rs:

#[tokio::main(worker_threads = num_cpus::get())]
async fn main() {
    // ...
}

3. File Descriptors (Linux)

Increase the limit before running:

ulimit -n 100000

Discussion

RustAPI is fast by default, but the OS often becomes the bottleneck using default settings. panic = "abort" reduces binary size and slightly improves performance by removing unwinding tables.
