The Value of Leveraging Virtualization for Application Performance Testing
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 [...]

Wednesday, February 10, 2010
Since Steve Jobs presented Apple’s new addition, the IPAD, the press and the blogosphere are trying to assess the real impact on the new gadget. Is it a passing fad, like the Newton or the attempts by IBM to implement a tablet computer or a real game changer that finally, after almost 30 of personal [...]

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 [...]

Thursday, November 5, 2009
In the previous post we identified the Wide Area Network and the impairments that it introduces as a key reason for why a local user (let’s say in NYC) experiences a faster application than a user that is remote to his datacenter (let’s say in Tokyo). I also presented a question to the group: “We [...]

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 [...]

Thursday, September 17, 2009
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. [...]

Friday, August 14, 2009
In my line of work, I get to assist many clients with analyzing the impact of an upcoming data center relocation on the performance of business applications. Many clients don’t know exactly what application performance to expect post the data center move. The main concern is that once all the applications start to operate across [...]

Wednesday, March 25, 2009
One of my favorite partners to work with is LoadTester. Not only are they competent and efficient, but they are nice and will tell you what they really think. Their latest update on HP’s latest release of LoadRunner 9.5 goes into a lot more detail than any readme file will, with perspective and colorful commentary [...]
Continue reading...Adding Network Analysis to a LoadRunner 9.5 Scenario
Tuesday, March 10, 2009
In a previous post I explained how to add network conditions to a LoadRunner scenario, answering the question, “How will this application perform in a remote site?” The results from running a LoadRunner test with network conditions will highlight transactions that perform well under network conditions as well as pinpoint transactions that will degrade in [...]

Friday, March 6, 2009
Earlier this week, Shunra announced the release of a new product, VE Desktop for HP Software 5.0. This product is embedded into HP’s LoadRunner 9.5 and Performance Center 9.5 products and from the surface, looks a lot like a previous feature in LoadRunner called Mercury WAN Emulation (MWE). Because of the obvious similarities, there have [...]
