Application developers have also figured out clever ways of working around network latency problems, but there are limits to what can be done. Packet loss in TCP connections results in retransmissions which can introduce significant latency. Below is the beginning of a TCP handshake. Router hops introduce the most.

Since the kernel is basically the software layer between the applications you’re running and the underlying hardware, eBPF operates just about as close as you can get to the line-rate activity of a host. When an application runs from the user space, it interacts with the kernel many, many times. How does eBPF work?

To be more specific: slowness can be introduced as your digital connection traverses your PC, the local wifi/wired connection, the local ISP, the Tier 1 or Tier 2 provider, or the CDN that provides the hardware which hosts the web server running the application. The use of ICMP vs. TCP or UDP to carry the ping can also be a factor.

In most cases, these patterns are evaluated on a single network packet, rather than a sequence of flows between a client host and a server.

If the link is congested, then a basic NetFlow tool function allows you to double click on that, and you can see that the link is full because there’s tons of traffic due to the database servers syncing. The link may be almost full, but there may be no TCP retransmits, and the latency may be good. So the data’s coming from the servers.
