In this comparison of Redis vs Memcached, we strip away the complexity, focusing on each in-memory data store’s performance, scalability, and unique features. Redis is better suited for complex data models, and Memcached is better suited for high-throughput, string-based caching scenarios.

As I see it, there are two main issues when it comes to measuring performance changes (note, not improvements , but changes) in the lab: Site-speed is nondeterministic 1. We can take reasonable measures (always refresh from a cold cache; throttle to a constant network speed), but we can’t account for everything. Isolate Your Impact.

Quality gates are benchmarks in the software delivery lifecycle that define specific, measurable, and achievable success criteria a service must meet before moving to the next phase of the software delivery pipeline. Automating quality gates creates reliable checks and balances and speeds up the process by avoiding manual intervention.
