Load Tester™ New Features
New in 4.0 Release
The latest version of Load Tester is most definitely our greatest. That’s because Load Tester 4 was designed to generate loads from both inside the network and outside the network using the cloud. How cool is that? Infinitely.
Load Tester™ is Enterprise Class software that has been under development for ten years, and has a huge number of features. If you want to find out if its right for your situation just contact us.
Amazon Cloud-based Load Engines
Enterprise-grade Load Tester 4 lets you see how your website performs from outside your network, without configuring complicated and pricey external load generators. Within five minutes the infrastructure required to generate up to 100,000 concurrent users is automatically setup in the cloud and ready to start testing. And of course, as with all previous versions of Load Tester, no hand coding.
Load Tester 4 is light years ahead of other web-based cloud load testers, and is capable of handling even the most complicated websites. Load Tester 4 automatically handles basic features like session tracking, VIEWSTATES and data customization with ease, and performs brilliantly with tons of other more important parameters.
The latest browsers
The latest browsers, IE8, Firefox 3.5, and Safari 4 have been released and their client-side performance is greatly improved over the previous versions. The only problem is one of the main changes in these browsers is to triple the number of open sockets to the web servers, which our research shows can reduce website capacity by up to 60%. Its a good idea to test now to see how your website is going to react before you start seeing performance problems with the latest browsers.
Better load generation
Now that load engines can be virtualized at the press of a button monitoring their performance becomes even more critical. The Engines section in report helps the tester demonstrate that the test was performed under optimal conditions by charting each engine in 4 resource utilization plots (cpu, memory, in & out bandwidth).
The steal percentage on linux is a new metrics designed for specifically for monitoring virtualized servers. It measures how much of the physical hardware that would have been available to the virtualized system under test is being "stolen" by another virtual machine on the same hardware. This parameter is collected both on monitored servers and load engines.
More flexible tests
More flexible ramping allows variable-length ramps (used to be fixed 1-minute). Ramp durations and periods can now be specified in seconds for more precision.
Improved load-distribution algorithms allow faster and more flexible ramping, allowing for shorter tests when large numbers of users are tested.
Mass-edit operations make it easy to change hostnames, path segments, proxy configuration and SSL usage on an entire testcase.
Servers view and Engines view now support charting any server/engine metric live during the test.
