your `Cargo.toml`:
+
+```toml
+[dependencies]
+datafusion = { git = "https://github.com/apache/arrow-datafusion.git";,
features = ["simd"]}
+tokio = { version = "^1.0", features = ["macros", "rt", "rt-multi-thread"] }
+snmalloc-rs = {version = "0.2", features= ["cache-friendly"]}
+num_cpus = "1.0"
+
+[profile.release]
+lto = true
+codegen-units = 1
+```
+
+Then, in your `main.rs.` update the memory allocator with the below after your
imports:
+
+```rust
+#[global_allocator]
+static ALLOC: snmalloc_rs::SnMalloc = snmalloc_rs::SnMalloc;
+```
+
+Finally, in order to build with these optimizations `cargo nightly` is
required. Based on the instruction
