How Raygun increased transactions per second by 44% by removing Nginx

Here at Raygun, improving performance is baked into our culture. In a previous blog post, we showed how we achieved a 12% performance lift by migrating Raygun’s API to .NET Core 3.1. In publishing this, a question was asked on Twitter as to why we still use Nginx as a proxy to the Raygun API application. Our response was that we thought this was the recommended approach from Microsoft. It turns out this has not been the case since the release of .NET Core 2.1.

Debug JavaScript in Microsoft Edge in 7 steps

This article will focus on debugging JavaScript code within Microsoft Edge Developer Tools. The Edge DevTools are a powerful toolset built into the Edge browser on Microsoft Windows 10. The DevTools are also available as a standalone app to download from the Microsoft Store, if one prefers to run them separately from Edge itself. We’ll be using Raygun Crash Reporting to find the stack trace and the line of code the error occurred on. You can sign up for a free 14-day trial here.

Detect Content Security Policy (CSP) violations with Raygun

A Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of attacks, including Cross-Site Scripting (XSS) and data injection attacks. These attacks are used for everything from data theft to site defacement to the distribution of malware. Whilst blocking attacks is important, it is also useful to be notified of attacks when they happen. A breach could bring your organization to a halt — from broken webpages to data breaches.

Real User Monitoring vs. APM: What's the difference?

As modern development practices evolve at rapid rates we must stay focused on what makes for a great experience; fast, flawless software. In the pursuit of building fast, performant software, you’ve likely come across performance monitoring products like Real User Monitoring (RUM) and Application Performance Monitoring (APM). In this article, we go deeper into how using RUM and APM can help you and your team build better software experiences.

Achieving a 12% performance lift migrating Raygun's API to .NET Core 3.1

Here at Raygun, improving performance is baked into our culture. We don't just think about our application performance, but more broadly, we look at our own infrastructure and ask if there's anything we can do to make it more performant for our business and for our customers. Two years ago, we switched our API from Node.js to .NET Core and achieved a 2000% increase in throughput. To continue that story, we recently upgraded .NET Core 2.1 to 3.1 and saw a 12% increase in performance. We enjoy presenting our performance findings, so in this post, we'd like to give some context into why we upgraded and the conditions that helped us achieve the 12% performance lift.
