+## Slow Debug Recompilations
+
+If you experience slow compile times when iterating with lots of templates,
+you can compile Askama's derive macros with a higher optimization level.
+This can speed up recompilation times dramatically.
+
+Add the following to `Cargo.toml` or `.cargo/config.toml`:
+```rust
+[profile.dev.package.askama_derive]
+opt-level = 3
+```
+
+This may affect clean compile times in debug mode, but incremental compiles
+will be faster.
