In this blog post, we will discuss the best practices on the MongoDB ecosystem applied at the Operating System (OS) and MongoDB levels. Operating System (OS) settings Swappiness Swappiness is a Linux kernel setting that influences the behavior of the Virtual Memory manager when it needs to allocate a swap, ranging from 0-100.

On high-performance multi-core systems all the supported databases can return performance in the many millions of transactions per minute. To benchmark a database we introduce the concept of a Virtual User. For this reason we need to implement our database sessions in the form of operating system threads. The Python GIL.

SQL Server relies on Forced-Unit-Access (Fua) I/O subsystem capabilities to provide data durability, detailed in the following documents: SQL Server 2000 I/O Basic and SQL Server I/O Basics, Chapter 2. Durability: “In database systems , durability is the ACID property which guarantees transactions that have committed will survive permanently.
