Well I don't intend to mean they are the same, but optimization to improve the latency can often improve throughput as well. Whatever...

You can expand on a question without being douchey.

OP is right that you can often improve both at the same time, it's just worded poorly.

Agreed. When dealing with low hanging fruit, you often improve both.

Later though… once your system is somewhat optimized, you will tend to make latency vs throughput decisions. For most people though, slight changes to latency are the cost to large increases in throughput, but that may just be my experience.

Please do read a bit about history of TCP and how latency impacts the overall throughout. It's a classic thing and applies to any processing where you need results of some steps to proceed.
