Push-button load testing inside the cloud means success for eArcu
Here are a few quick pointers for checking your Load Test, to see if you are ready to run. Feel free to check back, as this list may be updated from time to time.
Test Planning:
Have the appropriate parties been notified of the test?
Do any of the servers have scheduled jobs during the test window? Automatic backups or other maintenance windows that are scheduled during normal down-time or idle-time can have surprising results during a high volume test.
Is the firewall going to be an issue? When using a small set of external IPs to generate load, make sure the firewall administrators … Continue reading »
One of the main features I wanted to design into a load testing tool was the ability to “just work” for most things. Reverse engineering how a website works just to get a load test done is no fun, especially since its possible to automate much of the process and you can spend your time testing instead. Which is why it was great to get an email from someone trying our demo who noticed we handled his dynamic SID configuration in a few minutes where his previous load testing tool took four hours.
The specific thing I was referring to … Continue reading »
Amazon’s Elastic IPs provide an easy way to assign a fixed IP address to cloud-based load engines – which would typically have a different IP address each time one is created.
If you’ve installed Load Tester™ on a workstation, and are in the process of upgrading to a new workstation, you may be wondering how to move your Load Tester™ installation between the workstations. For version 4.0, this is not a difficult process, and generally can be completed in four steps:
Install a copy of Load Tester on your new workstation. New installers are available at www.webperformance.com/download
Copy the .WPT files from the old workstation (if they are not already saved on a network share). These files contain your recorded & configured testcases, as well as load test results.
Transfer your License … Continue reading »
At Web Performance we’re interested in things that go fast, whether they’re websites or cars, so it’s only natural that we are sponsoring Jason Tower’s inaugural road racing season in his BMW Spec E30. As a rallycrosser myself, I’m excited to be involved with grassroots racing as Jason – pardon the pun – stress tests his E30 on courses from VIR to Mid Ohio to Road Atlanta. He’s so good, he can turn left AND right!
The Spec E30 concept is cool: drivers compete based on their driving skills, not their wallet, which is where you get the … Continue reading »
Learn how to diagnose the tricky situation where a server periodically hangs on pages.
By analyzing data against applied user levels, rather than only against elapsed time, Load Tester permits better understanding of performance and of capacity.
There is a new Load Testing 101 post over on the Dynatrace Blog. Overall, I think it is a pretty good article. However, it illustrates some of the fallacies of load testing that we hear from time to time. In this article, I want to dispel a fallacy that might be inadvertently reinforced by that post. Please note that I don’t want to speak for the authors – so I encourage you to read their article and judge their meaning for yourself.
The performance improvements in the latest browsers (Internet Explorer 8.0 and Firefox 3.5) have been eagerly awaited for many months…though they come at a price.
