Key Takeaways Critical performance indicators such as latency, CPU usage, memory utilization, hit rate, and number of connected clients/slaves/evictions must be monitored to maintain Redis’s high throughput and low latency capabilities. It can achieve impressive performance, handling up to 50 million operations per second.

Before you begin tuning your website or application, you must first figure out which metrics matter most to your users and establish some achievable benchmarks. Wait time: Sometimes called average latency, wait time refers the amount of time a request spends in a queue before it gets processed. What is Performance Testing?

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. I love short benchmarks like this as I can disassemble the resulting binary and ensure that the compiled instructions match my expectations, and the compiler hasen't messed with it. ## 6. include <sys/time.h>

This post complements the previous best practice guides this time with the focus on MySQL and MariaDB and achieving top levels of performance with the HammerDB MySQL TPC-C test. InnoDB is the storage engine that will deliver the best OLTP throughput and should be chosen for this test. . HammerDB difference from Sysbench.
