Understanding & Profiling C# Async Await Tasks
Microsoft and the .NET community have made asynchronous programming very easy with their implementation of async await in C#. The latest versions of ASP.NET heavily utilize it to improve performance. Many performance monitoring and profiling tools struggle to support and visualize the performance of asynchronous C# code. Stackify’s Prefix & Retrace products both have excellent support for applications using C# async await. …
List of Java Profilers: 3 Different Types and Why You Need All of Them
Debugging performance issues in production can be a pain and in some cases impossible without the right tools.

Essential Application Profiling Tools to Find Bugs in Your Code
Developers love tools, and they tend to use a lot of them. Many of them are such a normal part of our daily lives and toolchain that we don’t even think of them as tools anymore. Your computer, the Internet, a simple text editor, and source code repositories are a good example of this. They are just fundamental things we …
Prefix: A lightweight ASP.NET profiler helping you write better software
Of all the modern development practices which I use day to day, none other has been more beneficial to me than the introduction of quick feedback loops in my workflow. Although a concept made popular by the Agile methodology and practices, it’s something most of us deal with when we invoke the compiler (or linter) which tells us if our …
The Best Log Viewer for Developers in the Universe
It is hard for developers to imagine troubleshooting applications problems without debug logging.

Getting to Production Faster – With More Confidence
“I want to spend less time in QA, but I still want to go to production with full confidence in the release. The more time we spend in QA, the more time we waste – we just can’t expect to catch everything in testing, our product is too complex and our QA team is too small. Can you guys help …
How we named Prefix: It was a little hairy
Naming things is hard—unless it’s a dog or a kid. That’s easy (apparently)! A brand or product name is a totally different kind of anxiety. Creating the product is comparatively easy. This is the story of the name that almost won, how it came to be, and how it continues to live exactly where it should—in the dark recesses of our code. …
Why Calling a Web Service Takes Longer Than You Think
There are a lot of ways to make a web service or web request in .NET. Common libraries include HttpClient, WebClient, WCF generated clients, RestSharp, and, of course, your low-level HttpWebRequest/HttpWebResponse objects.

Our goal with Prefix and the Stackify APM is …
Prefix vs Glimpse: SQL Queries
This article is meant to illustrate a high-level comparison of how Prefix and Glimpse track SQL queries. While the two tools are similar (they’re both designed to help us understand different elements of our code’s performance) the two products have some unique pros and cons. Here’s a comparison based on our own experience with both tools. How to enable Glimpse …
How to Measure Real World SQL Query Performance for ASP.NET
Almost every ASP.NET application uses some sort of database. But from my experience, the reporting of how long SQL queries take is wildly inaccurate. In this article I’m going to explain why, and show you how you can see the real amount of time that your queries take. This article is really specific to Microsoft SQL Server but the principle …
