In the context of web development, performance testing entails using software tools to simulate how an application runs under specific circumstances. Just because everything works perfectly during production testing doesn’t mean that will be the case when your website is flooded with traffic. What is Performance Testing?

As defined by the Google SRE initiative, the four golden signals of monitoring include the following metrics: Latency. Latency is the amount of time, or delay, a service takes to respond to a request. Traffic refers to the amount of user demand, or load, is on the system. Monitoring can provide a way to differentiate between.

DLVs are particularly advantageous for databases with large allocated storage, high I/O per second (IOPS) requirements, or latency-sensitive workloads. Overall, adopting this practice promotes a structured and efficient storage strategy, fostering better performance, manageability, and, ultimately, a more robust database environment.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. Since instances of both CentOS and Ubuntu were running in parallel, I could collect flame graphs at the same time (same time-of-day traffic mix) and compare them side by side. But I'm not completely sure.

Why ProxySQL? I will eventually increase them if I see the need.

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).
