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.

Let’s look at how the workloads behave when running on an identical system We ran both sysbench and HammerDB on a system with: Processors: Two Intel Xeon 8360Y processor sockets (36 Core/72 Threads per socket). Operating System: Ubuntu 22.04 For the experiments in this blog, we did not tune the system.

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.

For most high-end processors these values have remained in the range of 75% to 85% of the peak DRAM bandwidth of the system over the past 15-20 years — an amazing accomplishment given the increase in core count (with its associated cache coherence issues), number of DRAM channels, and ever-increasing pipelining of the DRAMs themselves.

Prior to SQL Server 2012, the maximum server memory value only applied to the bufferpool, so customers needed to limit the amount of memory the bufferpool could use to save memory for the operating system and other processes. I tend to recommend increasing this value to a higher number after examining the Plan Cache.

Stable media is commonly physical disk storage, but other devices and certain caching facilities qualify as well. Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. This cache is often supported by a battery-powered backup facility.

Since operating system dark modes have become more prevalent, I also subtly alter the lightness and saturation of colors in my palettes, so they appear more vibrant against dark backgrounds. CSS transforms are ideal tools for fine-tuning the size and position of elements within grids’ constraints. Left: My color palette.
