Updated, i reproduced it now with a simple list cases, i will further
investigate:
```rust
let v1 = FixedSizeListArray::try_new(
Arc::new(Field::new_list_field(DataType::Int32, true)),
1024,
Arc::new(create_primitive_array::<Int32Type>(1024 * 1024, 0.0)),
None,
)
.unwrap();
let v2 = FixedSizeListArray::try_new(
Arc::new(Field::new_list_field(DataType::Int32, true)),
1024,
Arc::new(create_primitive_array::<Int32Type>(1024 * 1024, 0.0)),
None,
)
.unwrap();
c.bench_function("concat fixed size lists", |b| {
b.iter(|| bench_concat(&v1, &v2))
});
fn bench_concat(v1: &dyn Array, v2: &dyn Array) {
hint::black_box(concat(&[v1, v2]).unwrap());
}
```
