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 .

OCTOBER 19, 2020

Reconstructing a streaming session was a tedious and time consuming process that involved tracing all interactions (requests) between the Netflix app, our Content Delivery Network (CDN), and backend microservices. The process started with manual pull of member account information that was part of the session.

As datasets continue to grow in size, the amount of RAM required to store and process these datasets also increases. Benchmark before you decide. But also larger log files mean that the recovery process will be slower in case of a crash. If you see concurrency issues, you can tune this variable.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. What about short-lived processes, like a service restarting in a loop? I've shared many posts about superpower observability tools, but often humble hacking is just as effective. These can be invisible to top(8).

This post at an entry-level discusses the options you have to improve log throughput in your benchmark environment. . Additionally for the log disk component it is latency for an individual write that is crucial rather than the total I/O bandwidth. A good example of how tuning is an iterative process.

It's an ongoing, iterative process. Two of them are particularly gnarly: fine-tuning rules to perfection and managing a WAF over a multi-CDN architecture. Similarly, a rule that works perfectly on one CDN may trigger false positives or negatives on another due to slight variations in how each CDN processes web traffic.

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. Measurements refer to specific data points, such as the number of seconds it takes to process a request. What is Performance Testing? What’s the difference?

For anyone benchmarking MySQL with HammerDB it is important to understand the differences from sysbench workloads as HammerDB is targeted at a testing a different usage model from sysbench. maximum transition latency: Cannot determine or is not supported. . Fortunately HammerDB allows all of this process to be automated.

Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. Because the log record for a page modification does not ​​ exist, the recovery process cannot determine the proper transactional state of the page. Latch page 150 to prevent further modifications.
