A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. What about short-lived processes, like a service restarting in a loop? This server is spending about a third of its CPU cycles just checking the time! What on Earth is Ubuntu doing that results in 30% higher CPU time!?

Micro-optimizations are great for keeping performance on track, but it’s critical to have clearly defined targets in mind — measurable goals that would influence any decisions made throughout the process. Also, as Patrick Meenan suggested, it’s worth to plan out a loading sequence and trade-offs during the design process.
