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. Microbenchmark os::javaTimeMillis() on both systems.

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. Similarly, an increased throughput signifies an intensive workload on a server and a larger latency.

This test helps to measure the speed, scalability, reliability, and stability of software under varying loads, thus it ensures stable performance. It checks the system’s responsiveness, speed, and stability under varying workload conditions. Today, let's learn more about this testing type in depth. What Is Performance Testing?

Introduction Caching serves a dual purpose in web development – speeding up client requests and reducing server load. For vertical scaling, Memcached allows augmenting existing servers with additional CPU cores and memory, thereby enhancing the capacity of the caching pool to manage higher traffic volumes and larger data loads.

Data collected on page load events, for example, can include navigation start (when performance begins to be measured), request start (right before the user makes a request from the server), and speed index metrics (measure page load speed). RUM, however, has some limitations, including the following: RUM requires traffic to be useful.

One benchmark I wrote measured the L2 cache latency. I don’t remember what the L2 cache latency was but do remember that the latency varied depending on which CPU core I ran it on. The L2 latency from CPU core 0 was pretty reliably four cycles lower than the L2 latency from CPU core 1 or 2. So, anyway. mm distance!

CDNs use load-balancing techniques to distribute incoming traffic across multiple servers called Points of Presence (PoPs) which distribute content closer to end-users and improve overall performance. When an edge server goes down, end users in the affected region may experience an increase in latency for that specific location.

Improving latency for one scenario can degrade it in another. The predominant answer: a unified theory of web performance.

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. And those speeds aren’t constant.
