This post explains why HammerDB made the language decisions it made to make it the best performing and most usable database benchmarking software. To benchmark a database we introduce the concept of a Virtual User. So having an application client mutex lock that artificially stalls our Virtual Users does not sound good.

My blog has been quieter than I would have liked; hopefully I can find more time to document some of these, maybe in series form. halt (); Some sort of very early exception handler; better to sit busy in an infinite loop than run off and destroy hardware or corrupt data, I suppose. This is documented further in linux-insides.

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 the other hand, MongoDB schema design takes a document-oriented approach. Without further ado, let’s start with the OS settings.

In the simplest case, you have a growing workload, and you optimize it to run more efficiently so that you don’t need to buy or rent additional hardware, so your carbon footprint stays the same, but the carbon per transaction or operation is going down.

Linux has been adding tracing technologies over the years: kprobes (kernel dynamic tracing), uprobes (user-level dynamic tracing), tracepoints (static tracing), and perf_events (profiling and hardware counters). They use third-party software like Docker or Kubernetes to simplify their administration. People rarely create them manually.

Mobiles have different models, screen resolutions, operating systems, network types, hardware configurations, etc. Also, how to test the hardware of the mobile phone itself, is it supporting all the software as it should? Let us have a look at the most popular types of mobile testing for applications and hardware.
