“Cross layer comprehension” - what is that? Wanna move computation to the NIC ?
- foobiekr 4y agoIt is useful to understand the underlying layers so as to take advantage of what they are good at and not end up in the position of relying on operations where they perform badly. "What is are the natural, performant operations for the layer below me? How can I construct my solution from these operations instead of pretending the layers are orthogonal?" A good example would be the linear read/write performance of harddisks. If you had the option to avoid random access and take advantage of read-ahead and other methods you'd have seen much better performance than an approach that ignored this behavior. There are many, many examples of this.
