An analysis of performance evolution of Linux’s core operations

The Morning Paper

For the rest of us, if you really need that extra performance (maybe what you get out-of-the-box or with minimal tuning is good enough for your use case) then you can upgrade hardware and/or pay for a commercial license of a tuned distributed (RHEL). A second takeaway is this: security has a cost! Measuring the kernel. Headline results.

MySQL Capacity Planning

Percona

As such, one of the more common questions I get from my clients is whether or not their system will be able to endure an anticipated load increase. Hardware considerations The first thing we have to consider here is the resources that the underlying host provides to the database. Let’s take a look at each common resource.

A Spectrum of Actions, Part II

J. Paul Reed

Even though that remediation task was pretty minor — tweaking some low-level hardware settings on each physical server and rebooting — and could have been done quickly enough, there was intense debate on whether it should be done. In practice (and I’ve done this exercise with teams), this spectrum can provide useful insight.

COVID-19 Hazard Analysis using STPA

Adrian Cockcroft

Picture taken by Adrian March 17, 2020 A resilient system continues to operate successfully in the presence of failures. There are many possible failure modes, and each exercises a different aspect of resilience. Hence, one way to reduce risk is to make systems more observable. The first technique is the most generally useful.

How to Assess MySQL Performance

HammerDB

Instead, focus on understanding what the workloads exercise to help us determine how to best use them to aid our performance assessment. Therefore, before we attempt to measure our database performance, we should know the system or cloud instance to be tested in detail. Operating System: Ubuntu 22.04 Operating System: Ubuntu 22.04

A persistent problem: managing pointers in NVM

The Morning Paper

At the start of November I was privileged to attend HPTS (the High Performance Transaction Systems) conference in Asilomar. 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. PLOS’19.
