Even if it is 4G (5G, or whatever else) that doesn’t exactly guarantee you’ll be getting the amazing, theoretical speeds promised. Once a new network does get rolled out, it takes years for carriers to optimize it to try and close in on the promised bandwidth and latency benchmarks.

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. When the word “performance” is heard, most people immediately think of speed. An interruption in data flow due to limited capacity is called a bottleneck.

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.

In addition, such custom systems could only be benchmarked once they were deployed, so by the time multiple layers of management had each added a 50% safety margin to the initial SWAG , it was not unusual to see them running at 10% of capacity (but 150% of the lucky hardware salesman’s annual quota).

Real user monitoring (RUM) is a performance monitoring process that collects detailed data about users’ interactions with an application. RUM collects data on each user action within a session, including the time required to complete the action, so IT pros can identify patterns and where to make improvements in experience.
