Andreas Grabner described how he used the Compuware APM PureStack technology
to identify the server-side performance issues during a recent load test run
against the Compuware APM Community Portal, a production application used by
our customers. He was able to quickly identify the CPU bottleneck that caused
the performance degradation in the server environment, leading to an almost
immediate resolution of the issue.

that shows the Hotspots of "Horizontal" Transaction as well as the "Vertical"
But what about the external performance recorded during this load test? What
would a customer have experienced if they had tried to access the site during
this time? Well, at the peak of the test, I used WebPageTest to capture a
video of the APM Community Homepage loading (Note: The video has been... (more)
No matter which team you were cheering for (or if you even watched the game
at all), Super Bowl Sunday 2013 was more than a football game. Since the late
1990s, Super Bowl advertisers have tried to successfully link their TV ads to
their online properties, sometimes with mixed results. Even 15 years later,
companies can't always predict how well their sites will perform on the big
day. But unlike the early days of TV/online campaigns, the problems are more
complex than a site going down under heavy traffic.
This year, some of the world's premier brands spent millions of dollars on... (more)
Complexity is the new reality of web and mobile applications with almost no
new release going out without the addition of services and applications
spread across many different companies. But the reality of this new
interrelationship is still the same: If a third-party Internet outage or
issue occurs, your brand is the one that is affected.
With up to 1,500 distinct third-party services available to choose from
around the world, it is sometimes difficult to even identify what a service
does when it appears in your applications. This forces your team to not only
be fully aware of... (more)
I started in the web performance industry - well before Application
Performance Management (APM) existed - during a time when external, single
page measurement ruled the land. In an ecosystem where no other solutions
existed, it was the top of the data chain to support the rapidly evolving
world of web applications. This was an effective approach to APM, as most
online applications were self-contained and, compared to the modern era,
relatively simple in their design.
A state-of-the-art web application, circa 2000
Soon, a new solution rose to the top of the ecosystem - the synth... (more)
It's been a busy and successful seven days for online retailers. Black Friday
and Cyber Monday traffic and sales were well above 2011, and there was the
extra benefit to those businesses that started deals on Thanksgiving Night.
The traffic data collected by the Compuware Ecommerce and Retail Real use
Monitoring index matched almost exactly the pattern seen by Akamai for all of
their US ecommerce and retail customers on the three busiest days.
Performance for many mobile sites has been cited elsewhere as being slow on
Black Friday and Cyber Monday. Looking at the... (more)
