HammerDB has graphical and command line interfaces for the Windows and Linux operating systems. An important concept was to simulate database users called Virtual Users in parallel (rather than concurrently) to accurately simulate a real database workload with multiple users running from separate systems.

This is a companion paper to the " persistent problem " piece that we looked at earlier this week, going a little deeper into the object pointer representation choices and the mapping of a virtual object space into physical address spaces. " Epheremal virtual addresses don’t cut it as the basis for persistent pointers.

A fairly large batch of papers focused on the study of novel OS architectures for systems with accelerators. GAIA proposed to expand the OS page cache into accelerator memory. The OS page cache serves as a cache for file accesses and plays an important role in core OS services, such as memory-mapped files.

Byte-addressable non-volatile memory,) NVM will fundamentally change the way hardware interacts, the way operating systems are designed, and the way applications operate on data. The beauty of persistent memory is that we can use memory layouts for persistent data (with some considerations for volatile caches etc.

A wide range of users with different operating systems, browsers, hardware configurations and other variables provides a wide sample size that helps developers discover as many issues as possible. This helps developers decide when to increase server disk space and power or whether or not using a virtual cloud server is optimal.

You might think of it like racing a car in virtual reality, where the conditions are decided in advance, rather than racing on a live track where conditions may vary. If throttling is applied at the operating system level , then the metrics match what a real user with those network conditions would experience.

As we are dealing with Docker images, I assume you have downloaded and installed Docker for your operating system. You will require VirtualBox (or a similar VM driver such as xhyve driver or VMware Fusion depending on your operating system) which enables Minikube to run a single-node Kubernetes cluster inside a VM.

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.

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.
