We’d like to get deeper insight into the host, the underlying operating system, and any third-party services used by our application. Tracking CPU usage helps identify performance bottlenecks, optimize resource utilization, plan for scalability, detect performance degradation, and monitor overall system health.

Nowadays, solid-state drives (SSDs) or non-volatile memory express (NVMe) drives are preferred over traditional hard disk drives (HDDs) for database servers due to their faster read and write speeds, lower latency, and improved reliability. Operating system Linux is the most common operating system for high-performance MySQL servers.

What we see here, though, is the emergence of the first iterations of the LLM SDLC: Were not yet changing our embeddings, fine-tuning, or business logic; were not using unit tests, CI/CD, or even a serious evaluation framework, but were building, deploying, monitoring, evaluating, and iterating! We tested both retrieval quality (e.g.,

This metric is interesting because we don’t always have the luxury of parallelizing every application we run, and our operating systems almost always process each call (e.g., Stay tuned! buffer copies for filesystem access) with a single thread. Why is the single-core bandwidth increasing so slowly?

The success of our early results with the Dynamo database encouraged us to write Amazon's Dynamo whitepaper and share it at the 2007 ACM Symposium on Operating Systems Principles (SOSP conference), so that others in the industry could benefit. This was the genesis of the Amazon Dynamo database.

This boils down to a single digit µs latency toleration in the tail for far memory, and in addition to security and privacy concerns, rules out remote memory solutions. Thus we’re fundamentally trading (de)-compression latency at access time for the ability to pack more data in memory. ML-based auto-tuning. Evaluation.

Are there inherent time relationships in the messages that need to be preserved as they travel across the system? The data shape will dictate capacity planning, tuning of the backbone, and scalability analysis for individual components. What message process warranty level do we require? At least once? At most once? Exactly once?

However in the Skylake microarchitecture (you can see a list of CPUs here ) the PAUSE instruction changed and in the documentation it says “the latency of the PAUSE instruction in prior generation microarchitectures is about 10 cycles, whereas in Skylake microarchitecture it has been extended to as many as 140 cycles.”

In this blog post, we will discuss the best practices on the MongoDB ecosystem applied at the Operating System (OS) and MongoDB levels. The main objective of this post is to share my experience over the past years tuning MongoDB and centralize the diverse sources that I crossed in this journey in a unique place.

Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. Many of these systems support I/O ordering with a stable media cache and subsequently combine and/or split I/O requests across available subsystem resources to complete the storing to physical media.
