...A MongoDB White Paper Performance Best Practices for MongoDB MongoDB 3.2 December 2015 Table of Contents Introduction 1 Pluggable Storage Engines 1 Hardware 2 Application Patterns 4 Schema Design & Indexes 5 Disk I/O 6 Considerations for Amazon EC2 7 Considerations for Benchmarks 7 We Can Help 9 Resources 9 Introduction MongoDB is a high-performance, scalable database designed for a broad array of modern applications. It is used by organizations of all sizes to power on-line, operational applications where low latency, high throughput and continuous availability are critical requirements of the system. For a discussion on the architecture of MongoDB and some of its underlying assumptions, see the MongoDB Architecture Guide. For a discussion on operating a MongoDB system, see the MongoDB Operations Best Practices. This guide outlines considerations for achieving performance at scale in a MongoDB system across a number of key dimensions, including hardware, application MongoDB Pluggable Storage Engines patterns, schema design and indexing, disk I/O, Amazon EC2, and designing for benchmarks.

...LINUX: Rute User’s Tutorial and Exposition Paul Sheer August 14, 2001 Pages up to and including this page are not included by Prentice Hall. 2 “The reason we don’t sell billions and billions of Guides,” continued Harl, after wiping his mouth, “is the expense. What we do is we sell one Guide billions and billions of times. We exploit the multidimensional nature of the Universe to cut down on manufacturing costs. And we don’t sell to penniless hitchhikers. What a stupid notion that was! Find the one section of the market that, more or less by definition, doesn’t have any money, and try to sell to it. No. We sell to the affluent business traveler and his vacationing wife in a billion, billion different futures. This is the most radical, dynamic and thrusting business venture in the entire multidimensional infinity of space-time-probability ever.” ... Ford was completely at a loss for what to do next. “Look,” he said in a stern voice.

I suppose I sort of knew. If I’d learned...
