#20 Shridhar M

Very good information about the different Performance tools which can be used for the Performance and Load testing.


Shridhar M

#21 Govardhan Reddy M

Nice article.
Before you dig in to any tool, I strongly recommend you to know:

1. what is performance testing?
2. what is load testing?
3. what is stress testing?

Just have one line definitions. But be very clear!!!

4. Is performance a functionality testing or non functionality testing?

My intention is not to confuse you. But my experience says that… above things must be cleared before proceeding further.

You know!
Tests can be of any type:
1. Constant load
2. Increased load
3. Random load

All depends on what is required/needed/demanded by client!!!

#37 Jose

We have been using AppLoader for a few months and it hasn’t given us anything to complain about. It is easy to use and has played every scenario we have scripted. There is a trial available to download at the website

#38 Jose

I apologize the correct link is

#39 Bob Bickel

We just introduced an (almost) free load testing service – RedLine13. The central service is free and spins up spot instances on a user’s own Amazon account (RedLine does not take any money) to run the load agents. So a 50,000 user test across 200 servers for an hour costs about $2.00. RedLine also sells Curated Open Source licenses to customers who want to run this in house.

#40 Dirk

You did not mention Openload from OpenDemand, very nice because no scripting is required…also the ex Compuware QALoad is now merged with Silk tools and is called Silk performer, sold by Microfocus. (very mature and capable, not just web – so comparable to Loadrunner)

#41 Anonymous

Am a test engineer and wanted to know the automation tool to test the desktop application, the tools you describe here all refers to the test of web application. So kindly which automation tool is suitable to stress test the desktop application.

#42 Jose

AppLoader is capable of stress testing any desktop application.

Hi Vijay,

This is extremely educational. I presently wish for to discover one and more performance tools. All are most significant Performance Testing tools.

As I was not conscious of so a lot of PT tools in the marketplace. Thanks for given this.

HP LoadRunner is a programmed performance tool and software allocates you to put off application performance troubles.

#49 Noel Slane

We are globally NO 3 by Market Share ( FACT ) behind HP and IBM rational. Silkperformer isn’t mentioned here? How can you claim accuracy around what is published. Our tool is enterprise strength and much more mature and robust than most of whats published.

A good article but we’re avery big omission!!!!

#50 Rushi

Please let me know the scope of performance testing and current financial requirement.

Appvance Enterprise is used by the worlds largest companies to drive apps up to millions of simulated users, just as users would use them. Deeper diagnoses of issues, re-use of functional scripts and easy to use record/play makes this the platform of choice for world-class organizations who cannot afford failure.

#56 Rich

This is a great list!

Appvance ( for performance, stress, functional, agile. Basically, all testing!

#57 Abhi

Bas pagal hoo gayee hai…

#58 lheytoz

how to stress and performance testing vb6 project??????

#59 Mo.

eggPlant Performance has been developed for over 20 years, whilst exclusively only UK based for most of those years.

They have many large corporate clients around the UK.

It has a very small footprint as the engine is coded in C++. However scripts can be written C#, Python, Java ….

Eggplant has great analysis, recording and scripting features. It can also handle many protocols.

Being a small company the support is great as you go straight to a developer mainly.

Costs are also competitive compared to the likes of HP, IBM etc.

#60 Tariq Ahmed

Hello all,

do we have any loadtesting tool which supports the .net technology. like sliverlight protocol even
i was using the latest Loadrunner11.52. which is not supporting the net.tcp binding,

do you know any load testing tools which supports the net.tcp binding.

#61 Henok

very helpful, Thanks!!!

Please guide me,as a software tester hows a career ,
is there any increment chances or growth of career in india or abroad?
is india best for this post,? explain brief..

#63 Mahesh

Hi All,

I could like to know what are the basic requirements for learning Performance Testing.


#64 Phil

I saw the question above about recommending a tool for testing mobile applications. As a Performance Tester I have personally found NeoLoad to be the easiest tool for getting the job done. There is now the option to integrate with functional testing products which has made it my go-to tool.

#65 Phil

Also, I forgot to mention to Tariq that NeoLoad covers the .net and Silverlight protocols.

#66 Thorskettle

I’m surprised that Visual Studio Load Test framework is not even in the list. It is one of the best load test platforms in the industry, if not the best. VSLT can generated load for any target hosted service open source or .Net. It allows you to use existing unit or integration tests that hit web services directly to include REST and SOAP or you can use the UI web recorder that will copy user actions and generate load with the recorded form posts. It collects performance counter information (windows platforms only). It automatically generates detailed reports to include graphs of cpu% utilization, latency, amount of user load, memory consumption etc. It automatically stores results for each test run. Open source is a good thing but the Microsoft development platform is world class and unmatched. Ask anyone who has moved from VS to XCode or Eclipse. They post their frustrations frequently.
