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 data over a longer period of
time shows that most sites varied little from their regular mobile
performance metrics, showing little or no performance difference compared to
the week leading up to these peak shopping days.
While this is good news for performance, it is bad news for mobile r... (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)
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.

In a Part 1, I demonstrated how to add more depth to the analysis of a
Compuware APM Web Load Test by combining the external load results with the
application and infrastructure data collected by the Compuware PureStack
Technology. But, now that we have tested the system once, what would happen
if we tested it again after we identified and "resolved" the issues we found?
Would running a test using the same parameters as in the initial test show a
clear performance improvement? Would the system be able to achieve the
desired load of 200 virtual users with little or no performance ... (more)
