Sometimes it is - TCP incast [1] in a fast LAN can be mostly alleviated by using switches with large buffers. Generally the higher throughput the bigger buffers you need unless having low latency is more important than low packet loss. The queue size is a tradeoff (as almost everything).

- jiggawatts 3y agoOne of our customers bought a special switch with huge buffers, on the order of hundreds of megabytes per port. It was a specialised SKU used only for dedicated backup networks. As in, networks that process only the traffic for disaster recovery backups. Latency on that type of network traffic is totally irrelevant, and the only thing that matters is achieving the maximum possible throughput — whatever the wire protocol allows. That’s the one time I’ve seen exactly 10 Gbps sustained.
