Load Testing & Monitoring Adobe Flex Applications

You use Adobe Flex!

See also:

Flex®, Adobe®’s development solution for rich Internet applications (RIA’s), is an open source framework for creating highly interactive and intuitive applications that deploy in an identical manner on most browsers, workstations and operating systems.

To communicate between the client workstation and the server, Flex relies on a protocol called AMF (Action script Messaging Format).

Neotys is Ready!

Thanks to Neotys, you can create scenarios to test and monitor your Flex applications’ behavior under stress and validate their performance while pinpointing any weaknesses.

Realistically testing and monitoring your applications with NeoLoad and NeoSense means you can deliver better performance to your customers at a lower total cost of ownership.

Flex Support

Since the Flex technology is based on a binary protocol, testing and monitoring Flex applications requires this protocol to be specifically supported.

Neotys’ Flex capabilities allow you to:

Record the AMF traffic to be played back (module not required for text or XML traffic).
Extract/replace AMF data during the test in order to variabilize the calls (the data is presented in XML format in the scenario).
Automatically handle the session IDs used by AMF.
Handle streaming channels (Push support required).


Certain Flex or Air applications may use the RTMP protocol as the transport layer. See NeoLoad’s RTMP support.


A short animation demonstrating a load test for Flex applications helps explain how Neotys supports this technology.

Customer Testimonial

Spectum K12

Based in Towson, MD, Spectrum K12 School Solutions Inc. is the leading provider of Response to Intervention (RTI) and special education IEP software serving 11% of the U.S. K-12 student population including 20 of the top 100 school districts in the United States.

We looked at a number of open source projects, and closed source products. None of them could match the simplicity and integrated experience that we saw with NeoLoad. The cost for NeoLoad also came in below some of the _supposedly_ more feature rich products out there. NeoLoad is by far the best combination of ease of use, functionality and price for load testing Adobe Flex applications on the market today.
