#![allow(non_snake_case, non_upper_case_globals)]
//! This benchmark tests just the overhead of Dioxus itself.
//!
//! For the JS Framework Benchmark, both the framework and the browser is benchmarked together. Dioxus prepares changes
//! to be made, but the change application phase will be just as performant as the vanilla wasm_bindgen code. In essence,
//! we are measuring the overhead of Dioxus, not the performance of the "apply" phase.
//!
//!
//! Pre-templates (Mac M1):
//! - 3ms to create 1_000 rows
//! - 30ms to create 10_000 rows
//!
//! Post-templates
//! - 580us to create 1_000 rows
//! - 6.2ms to create 10_000 rows
//!
//! As pure "overhead", these are amazing good numbers, mostly slowed down by hitting the global allocator.
//! These numbers don't represent Dioxus with the heuristic engine installed, so I assume it'll be even faster.
