Whether or not you are a fan of U.S. football – it was really hard to avoid this huge sports event on February 5. In addition to the actual game, it’s the Super Bowl commercials that – besides being very expensive to air – usually drive a lot of load on the websites of the companies th...
The success of the Web performance movement shows that there is increasing interest and value in fast websites. That faster websites lead to more revenue and reduced costs is a well-proven fact today. So being exceptionally fast is becoming the dogma for developing web applications. Bu...
Response times are in many – if not in most – cases the basis for performance analysis. When they are within expected boundaries everything is ok. When they get to high we start optimizing our applications.
So response times play a central role in performance monitoring and analysis. ...
Last week at Velocity we hosted a Birds of a Feather Session (BoF) and offered the attendees to analyze their web sites using dynaTrace Ajax Edition. Besides finding the typical performance problems (no cache settings, too many images, not minimized content, …) we found several sites t...
From time to time I access my work emails through Outlook Web Access (OWA) – which works really great on all browsers I run on my laptop (IE, FF, Chrome). Guessing that Microsoft probably optimized OWA for its own browser I thought that I will definitely find JavaScript code that doesn...
Just in time for the upcoming Webinar with The BonTon Stores, where we talk about the challenges in operating complex WebSphere environments, we had another set of prospects running their applications on WebSphere. Francis Cordon, a colleague of mine, shares some of the screenshots res...
Last time I explained logical and organizational prerequisites to a successful production level application performance monitoring. I originally wanted to look at the concrete metrics we need on every tier, but was asked how you can correlate data in a distributed environment, so this ...
In the last week my task was to create stable functional tests for a new eCommerce application. We picked several use cases, e.g.: clicking through the different links, logging in, searching for products and actually buying a product. We needed functional tests that run on both Interne...
When we get engaged with prospects that are interested in our performance management solution we walk them through a Proof of Concept. We let them install dynaTrace on their own prior to the actual POC. During the POC we ask them to exercise typical use cases on their application that ...
Recently there was a bigger discussion at dynaTrace around the cost of exceptions. When working with customers we very often find a lot of exceptions they are not aware of. After removing these exceptions, the code runs significantly faster than before. This creates the assumption that...

2010 is over and there has been a lot going on in the application performance space. We started this project at the beginning of the year inspired by Stoyan Stefanov’s performance advent calendar of 2009. (There is also one for 2010).
Now twelve months later we have our 2010 performan...
Alois Reitbauer explained in detail how dynaTrace continuously monitors several thousand URLs and uploads the performance data to the public ShowSlow.com instance. More and more of our dynaTrace AJAX Community Members are taking advantage of this integration in their internal testing e...
HTML5 introduces Application Cache, a new feature that enables you to make web apps and sites available offline. The new specification also provides an easy way to prefetch some or all of your web app’s assets (HTML files, images, CSS, JavaScript, and so on) while the client is still o...
So it seems that the Antivirus Add-On in Internet Explorer is causing a major impact in page load time. The AV Add-On needs to check all loaded JavaScript files for malicious code. In the example of Pedro and Frank they load jQuery, several jQuery plugins and some custom JS. This slows...

In his latest blog post, Steve Souders writes about the impact of performance on business success. I am not going to duplicate his content here as you can just go ahead and read his blog. I just want to highlight some very interesting points and give you some links to follow up resourc...
We all know that slow performance – and service disruption even more – affects our business services and eventually our revenue. At the same time we say that major parts of companies are not willing to invest in performance. In this article I will discuss why we find ourselves in this ...
Two weeks ago I co-hosted a Webinar with one of our users – Bill Mar, Director of Engineering Services from SmithMicro Software. SmithMicro provides the backbone of our digital life by connecting different digital devices together. In his role, Bill works in the Wireless Business unit ...
Amazon EC2 offers the CloudWatch service to monitor cloud instances as well as load balancers. While this service comes at some cost (0,015$/hour/instance) it offers useful infrastructure metrics about the performance of your EC2 infrastructure. While there are commercial and free tool...
SharePoint is without question a fast-growing platform and Microsoft is making lots of money with it. It’s been around for almost a decade and grew from a small list and document management application into an application development platform on top of ASP.NET using its own API to mana...
This time I take an a bit of an unconventional approach towards defining performance management. The idea for this article came through a number of customer engagements, where the same question came up over and over again: “How do we start with Application Performance Management and wh...
In my last two articles I wrote about how to Use BizTalk Performance Counters and how to Analyze Adapter and Pipeline Performance. In this final article I focus on Orchestration and calling external services.
Orchestrations can be as simple as reading a file from a file system, transf...
I had an interesting conversation with our Test Automation team lead Stefan – who Andi interviewed for our “Eating our own Dog Food ” article – on his experiences with the willingness of developers to write performance tests.
I asked a provocative question: do developers really want...
In Part I of this series I gave a general overview of BizTalk - the components that are involved in message processing and talked about how BizTalk specific performance counters can help spotting problematic areas. In this article we go beyond performance counters (even though we still...
In this third article of my Performance Almanac I discuss the role of overhead in performance management. As a performance management solution provider we’re frequently asked “How much overhead does your solution have?” This question is however a bit more complex to answer than just gi...
In order to ensure that end user response times are acceptable at all times it is necessary to measure the time in the way the end user perceives performance. Measuring and monitoring your live system is important to identify problems early on before it affects too many end users. In o...
Every time I work with one of our .NET customers to help them with managing their application performance I come across the same problems as seen with other clients before: lots of ADO.NET queries, many hidden exceptions in core or 3rd party .NET libraries, slow 3rd party components, i...
The dynaTrace AJAX Edition has been out there as an Alpha for a couple of weeks. It gave you the first impression what was to come. All the feedback we have received (like that from Steve Souders, and all that has come in via the contact form and the online forum) in that time made it...
