		<description><![CDATA[The Velocity Conference is the biggest and best web performance event in the field, and completely eclipses the testing conferences that add in performance as an afterthought.  Well, if truth be told its the only conference entirely on the subject, but that&#8217;s besides the point. The others might have a separate performance track, while this entire conference is devoted to building, testing, and operating high volume sites.

We&#8217;re a media partner this year, so if you&#8217;re thinking of attending be sure to use this 20% discount code:  WEBPER.

		<description><![CDATA[The 2012 car racing season got off to shaky start for our intrepid SpecE30 car and driver.  The driver, Jason Tower, is still not back 100% after surgery to repair a torn ligament in his hand, but none-the-less headed to the Virginia International Raceway to try his luck at a weekend of SpecE30 racing.  
The first race on Saturday was a disaster after a series of mishaps: 
&#8220;&#8230; a car went off in turn 3 on the first lap which summoned the
emergency vehicles to the spot.  The next time around another car
failed to see the yellow flag, &#8230; <a href="http://www.webperformance.com/load-testing/blog/2012/05/2012-racing-season-starts-with-a-crash/">Continue reading &#187;</a>]]></description>

		<description><![CDATA[One of the most frustrating jobs of writing a testcase is figuring out what went wrong when the test gives you an error message. Other tools may give you terse error messages, indicating there is a problem with the page. Load Tester 5 now makes this easy an automatic with a quick Visual Content Compare tool.
Let&#8217;s take a look at an example testcase using a simple workflow:

User logs into a web site
The user selects a link on the greeting page
User logs out

When working with a dynamic web application like this, when a page changes, that&#8217;s OK.

		<description><![CDATA[One of the easiest ways to create a system that keeps up with sudden increases in demand is to use auto-scaling systems offered by many cloud providers. The concept of bringing new systems online to handle demand is nothing new: this has also been used by CDNs for years to replicate high demand data to edge locations. Testing this type of system, however, can become more challenging when the auto-scaling relies on updating DNS records in order to route new users to new servers.
In Load Tester 5.0 and earlier, Load Tester could be set to <a title="Simulated DNS Load Balancing &#8230; <a href="http://www.webperformance.com/load-testing/blog/2012/04/testing-auto-scaling-servers-with-load-tester-5-1/">Continue reading &#187;</a>]]></description>

Load Tester LITE™ does have some restrictions, one of which being that you must verify that you own a server in order to run Load Tests against it. This process is referred to as Domain Ownership Verification. This process is not required for servers accessed through private IP ranges. Additionally, users with Load Tester PRO™ are not required to provide ownership verification.

		<description><![CDATA[Because load testing tools are usually priced by the number of simultaneous users it can generate, it is common to use fewer VUs (virtual users) than called for by the test plan. To compensate, testers may lower the think time (the time between pages) in order to move VUs more quickly through the testcases and achieve a higher transaction rate than actual users would produce. The transaction rate may also be increased by raising the simulated per-user bandwidth &#8211; again to speed the lower number of VUs through the testcases more quickly. The system capacity must then be extrapolated based &#8230; <a href="http://www.webperformance.com/load-testing/blog/2012/03/why-you-should-not-cheat-on-vus/">Continue reading &#187;</a>]]></description>

		<description><![CDATA[We frequently hear this question from customers during the evaluation/purchase process: &#8220;How do I know if Load Tester can generate the load I need?&#8221; We knew that question would be even more common when we released Load Tester 5, because it allows users to <a href="http://www.webperformance.com/load-testing/blog/2012/03/howto-generate-1-million-virtual-users-with-load-tester-5-0-pro/">load test 1 million users</a>. So to answer this question, we created a new version of Load Tester.
Load Tester LITE™ allows unlimited load generation for free. It has been suggested that LITE is a poor name for a load testing tool that can generate enough load to take down the vast majority of websites &#8211; &#8230; <a href="http://www.webperformance.com/load-testing/blog/2012/03/introducing-load-tester-lite/">Continue reading &#187;</a>]]></description>
