OK... I guess it is due to the computation of `block_id` and `block_offset`.
I found a machine with similar cores and profiling.
Then I found in the old and so good intel core, the `/` and `%` are really
expansive.
I am trying to optimize it.
```rust
impl GroupIndexOperations for BlockedGroupIndexOperations {
fn get_block_id(group_index: usize, block_size: usize) -> usize {
group_index / block_size
}
fn get_block_offset(group_index: usize, block_size: usize) -> usize {
group_index % block_size
}
}
```
```
