In the fast-paced digital world, where every millisecond counts, understanding the nuances of network latency becomes paramount for developers and system architects. Latency, the delay before a transfer of data begins following an instruction for its transfer, can significantly impact user experience and system performance.

When a user requests for feed then there will be two parallel threads involved in fetching the user feeds to optimize for latency. This will not only reduce the overall latency in displaying the user-feeds to users but will also prevent re-computation of user-feeds. Some of the keys of understanding the user network are listed below.

Penalty: Network Negotiation. Every new origin we need to visit needs a connection opening, and that can be very costly: DNS resolution, TCP handshakes, and TLS negotiation all add up, and the story gets worse the higher the latency of the connection is. On a slower, higher-latency connection, the story is much, mush worse.
