Python is a popular programming language, especially for beginners, and consequently we see it occurring in places where it just shouldn’t be used, such as database benchmarking. We use stored procedures because, as the introductory post shows, using single SQL statements turns our database benchmark into a network test).

To make data count and to ensure cloud computing is unabated, companies and organizations must have highly available databases. This guide provides an overview of what high availability means, the components involved, how to measure high availability, and how to achieve it. How does high availability work?

With so much at stake, database high availability and fault tolerance have become must-have items, but many companies just aren’t certain which one they must have. This blog article will examine shared attributes of high availability (HA) and fault tolerance (FT). What does high availability mean?

HammerDB is a software application for database benchmarking. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. The Transaction Processing Performance Council (TPC) was founded to bring standards to database benchmarking, and the history of the TPC can be found here.

HammerDB is a load testing and benchmarking application for relational databases. However, it is crucial that the benchmarking application does not have inherent bottlenecks that artificially limits the scalability of the database. Basic Benchmarking Concepts. To benchmark a database we introduce the concept of a Virtual User.

This technique saves two instructions in the prologue and epilogue and makes one additional general-purpose register (%rbp) available." It was also a virtual machine that lacked low-level hardware profiling capabilities, so I wasn't able to do cycle analysis to confirm that the 10% was entirely frame pointer-based.

To handle N parallel requests, N Lambda instances need to be available, and AWS will spin up up to 1000 such instances automatically to handle 1000 parallel requests. exports.handler = async function(event, context) { console.log("EVENT: n" + JSON.stringify(event, null, 2)); return context.logStreamName; }.

This post mines publicly available data on the pace of compatibility fixes and feature additions to assess the claim. As an engineer on a browser team, I'm privy to the blow-by-blow of various performance projects, benchmark fire drills, and the ways performance marketing (deeply) impacts engineering priorities. Higher is better.

MySQL triggers are a powerful tool for database administrators and developers, enabling them to automate tasks, enforce data consistency, and respond to events within the database seamlessly. These events, known as trigger events, can include actions like inserting, updating, or deleting records in database tables.

On August 7, 2019, AMD finally unveiled their new 7nm EPYC 7002 Series of server processors, formerly code-named "Rome" at the AMD EPYC Horizon Event in San Francisco. The initial reviews and benchmarks for these processors have been very impressive: AMD EPYC 7002 Series Rome Delivers a Knockout. Preferred AMD EPYC Processors.

It's challenging for teams climbing the maturity ladder to sift through the many available browser and tool-vendor data points to understand which ones to measure and manage. Strong Level 3 managers will realise that many performance events (both better and worse than average) occur along a user journey. but against what baseline?

The modifications persist even in the event of a system failure. Many of these systems support I/O ordering with a stable media cache and subsequently combine and/or split I/O requests across available subsystem resources to complete the storing to physical media. These systems must maintain support for I/O ordering.

In the end, it’s not the load events or server response times that define the experience, but the perception of how snappy the interface feels. Custom metrics measure a particular, custom event for the user, e.g. Twitter’s Time To First Tweet and Pinterest’s PinnerWaitTime. What does it mean? First Input Delay ( FID ) < 100ms.
