HammerDB doesn’t publish competitive database benchmarks, instead we always encourage people to be better informed by running their own. So over at Phoronix some database benchmarks were published showing PostgreSQL 12 Performance With AMD EPYC 7742 vs. Intel Xeon Platinum 8280 Benchmarks . 3823 2694 -- 0 4 4 2864 74.83

Some opinions claim that “Benchmarks are meaningless”, “benchmarks are irrelevant” or “benchmarks are nothing like your real applications” However for others “Benchmarks matter,” as they “account for the processing architecture and speed, memory, storage subsystems and the database engine.”

An example of a flame graph can be found below: Each box is a function in the stack, and wider boxes mean more time the system was busy on CPU on these functions. An example is kubectl-flame ( [link] ). For example, if you specify the NodeJS language, it produces the flame graph based on perf output. ✔ Launching profiler.

What the Lambda team introduced in 2018, for example, the new Firecracker VM, has since been fully rolled out. On the other hand, features needed for monitoring large applications, like memory dumps, code-level-visibility, or event loop metrics on Node.js In a future blog post, we’ll explain how to interpret Lambda metrics.

This post at an entry-level discusses the options you have to improve log throughput in your benchmark environment. . As HammerDB supports graphical metrics for Oracle, this provides the best illustration however the concepts apply in general terms to all databases. A good example of how tuning is an iterative process.

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. Quantitative performance testing looks at metrics like response time while qualitative testing is concerned with scalability, stability, and interoperability.

I then analyzed performance during the benchmark ([active benchmarking]), and used other benchmarks to confirm findings. For example, using my [perf-tools]: sudo./perf-tools/bin/funccount

A great example using the above techniques is the new Guardian newspaper website, currently in alpha.

Eventually, we resorted to caching the events in memory for a short duration and also tuning the GC settings on those nodes as we are doing a lot of young generation collections. We also generate quite a bit of internal application metrics using a home grown framework. How do you handle security? Miscellaneous. Who do you admire?
