Getting Accurate Results from Scalability Testing
None of us want our sites to crash like the Chase site outage in mid September. I’m not privy to the details of that site crash, but I can tell you that many sites degrade under peak user traffic unexpectedly and eventually crash. Why? It’s often incorrectly performed scalability tests. Over the years, I’ve met [...]

Wednesday, June 23, 2010
For those of you following my recent posts, this shouldn’t come as much of a shock. Shunra now has an exclusive offer for beta tester of HP’s LoadRunner in the Cloud that lets them use Shunra for HP Software FOR FREE!

Monday, June 7, 2010
My previous post about LoadRunner in the Cloud spoke about how Shunra™ for HP Software not only works well in clouds, but actually “completes the picture” for anyone conducting performance testing of applications that will be accessed remotely. I am not alone with these statements. SAP Labs, HP and Shunra are pleased to announce the availability of a new whitepaper, released today, June 7, titled, “Application Performance Testing in a Virtual Environment.”

Friday, March 12, 2010
Virtualization has emerged as one of the leading technologies in today’s market; enabling businesses to more effectively scale operations to meet demand while significantly reducing costs at the same time. Everyone seems to understand what virtualization is, but it’s actually rather difficult to define because the term is used interchangeably to describe a plethora of [...]

Friday, November 6, 2009
As a corollary to last week’s blog about hosted load testing, I thought it would be interesting to explain a little about using a cloud-based test environment to perform pre-deployment testing for a cloud-based application. That sounds like a lot of clouds! What we are simply trying to understand is where and how to deploy [...]

Friday, October 30, 2009
My friend Mark Tomlinson from HP recently wrote an informative blog about “Understanding the language of hosted load testing.” The blog touched on two competing approaches to application performance testing that were referenced as “behind the firewall” and “outside the firewall”. Behind the firewall testing usually means testing in a lab environment such as a [...]

In the previous post http://www.shunra.com/shunrablog/index.php/2009/08/14/data-center-relocation-questions-and-answers-part-1/ I presented an example of a common performance problem with applications that host executables on a remote shared drive. As common as that problem is, it is usually a legacy problem, most new applications follow a more best practices architecture usually involving a web based front end for the application. [...]

Wednesday, June 10, 2009
The Analysis application of LoadRunner 9.5 allows grouping transactions by emulated location. This enables users to see how each transaction performs in different locations. This is a very valuable feature but it is only available at analysis time, after the test stopped. In this post I’ll show how simple changes to the vugen scripts allow [...]
