Then we’ll look at how you can best utilize both to improve business outcomes. Monitoring vs. observability.

Already in the 2000s, service-oriented architectures (SOA) became popular, and operations teams discovered the need to understand how transactions traverse through all tiers and how these tiers contributed to the execution time and latency. The overall fallacy in this assumption becomes obvious when you look at the definitions of the terms.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

And, FMA instructions often have lower latency than a multiply followed by an add instruction. On the Xbox 360 CPU the latency and throughput of FMA was the same as for fmul or fadd so using an FMA instead of an fmul followed by a dependent fadd would halve the latency. Emulating FMA.
