Want to Stress Test Website with 10,000+ Users? Use WAPT Pro x64 Load Engine

In previous article we discussed on how WAPT pro performance testing tool can be used for website performance testing. But if you want to generate much higher load on web site you must use the latest x64 Load Engine release from WAPT team. This article and ultimately the testing tool is very useful for performance testers.

This is in fact most crucial test for time critical applications such as stock management systems which gets refreshed every minute creating huge load on web site as there are thousands of users accessing the web site at the same moment.

For such applications stress testing with more than 10,000 users is a basic test. The WAPT Pro comes with default “Load Agents” functionality to test average load on any web site. But for high capacity test with more than 10,000 users we can now leverage the power of x64 Load Engine extension.

x64 Load Engine is similar to Load Agents feature on WAPT Pro installation. The main difference is in the ability of load engine to generate huge load using 64 bit Windows systems. Using one 64 bit server you can dramatically increase the load testing capacity on web site under test. The x64 Load Engine can be configured in such a way that using slightly high end hardware you can easily generate more than 100k virtual users load on web site.

Assume that you want to stress test your web site with 100,000 concurrent virtual users. You can achieve this using 4 servers each with 25,000 virtual users. Setup this load engine on 4 systems and use them concurrently to achieve desired web site load. This powerful x64 Load Engine effectively utilizes the available memory resources on 64 bit system architecture.

WAPT Pro x64 Load Engine Installation:
– You can install x64 Load Engine on 64 bit version of Windows XP/2003/Vista/2008/Win7 OS.
– x64 Load engine works best on following hardware configuration:
Core i5/Phenom or CPU better than this, 8+ GB RAM and Gigabit Ethernet


How to install:    
x64 Load Engine is a WAPT Pro extension so it runs on WAPT Pro tool similar to Load Agents. To use this load engine you must have WAPT Pro installed first. You can download and install x64 Load Engine from below mentioned link. After installation you can start using load engine using the WAPT pro workplace itself.
Download WAPT Pro x64 Engine.

x64 Load Engine Pros:
– You can generate almost unlimited virtual users (test load) on Windows 64 system.
– Easy to install, learn and configure
Check out below screenshot to know the simplicity of x64 Load Engine Manager:

– No restrictions on the size of used virtual memory

x64 Load Engine Cons:
– No evaluation period available
– Works with WAPT Pro only

As said earlier in my comment, this tool is very useful for performance, stress & load testers. Other testers can get a glimpse of the performance testing scope which is very interesting to work on!

Please ask your queries in below comment section. Your feedback is always appreciated!

Hi, I am exploring tools to perform Stress/Load testing on Database. Just wanted to check whehter this tool support the functionality to perform load testing on Database. I have explored benchmark tool called Swingbench, but it supports only Oracle and TimesTen database. And also there is no support provided. It will be helpful if anyone can suggest any other tool to get my job done.
