+In `boreal`, different compiler profiles can be used, with one prioritizing scanning speed,
+and the other one prioritzing memory usage. Those two profiles are presented separately to
+show the memory consumption impact.

 Note that optimizing memory usage has not been a priority for the moment, as the focus was
 on optimizing performances. However, the next release will provide a way to proritize
