Top 15 Performance Testing Tools

• 100% Cloud-based, which gives our clients unlimited time savings and flexibility in monitoring their assets
• Proven, well-designed, scalable single instance (a.k.a. multi-tenant) software-as-a-service platform which allows the seamless delivery of new features
• Self-updating, flexible, mobile remote agent for internal monitoring, which works seamlessly through corporate firewalls
• Integrated, hybrid platform of external and internal monitors which utilizes benefits of both agent-based and agent-less technologies

• Accelerates problem resolution -- by finding performance or scalability problems early in development cycles or after one load test
• Reduce performance rework that slows down projects and eats software development budget

• Identifies the presence and cause of system performance bottlenecks
  
• Offers flexible modeling and emulation of diverse user populations while minimizing the memory and processor footprint
  
• Reports in real time to enable immediate recognition of performance problems and renders an HTML browser-like view of Web pages in the test
  
• Creates code free tests quickly without programming knowledge

• Load Test any application, any environment
• End to end testing from the end user perspective
• 360° view of app performance

• A business-based approach in conducting your performance tests
• Simple to use means a high capacity to simulate load
• Automatically detecting and analyzing anomalies 
• Automatic report creation
• Support for different environments

• Diagnose and resolve failing requirements related to performance.
• Validate and quantify application architectures
• Quantify and provide context to performance defects, showing developers where bottlenecks or failures occur in production.

• Minimum system impact
• True representation of your business and users
• Analysis for web performance improvement
• Integrated tools in the Apica WebExcellence suite 

Forecast tests the reliability, performance and scalability of IT systems by realistically simulating from one to many thousands of users executing a mix of business processes using individually configurable data. Forecast is capable of simulating high user concurrency without the expense and management overhead of excessive hardware. Forecast targets a wide range of technologies including Web/HTTP, Web Services, client-side Java, client-side .Net, Citrix, GUI replay, and network level messaging.

 Stress testing software should not stress you out.  WebLOAD Professional is RadView’s award-winning software for performance testing of internet applications. Key features of WebLOAD software are as follows:

• Expert knowledge: Highlights performance bottlenecks by comparing against industry best practices
• Rich template gallery: Provides a repository of predefined report templates that are based on industry best standards
• Advanced data analysis: Zoom in, filter, transpose and use thresholds and percentiles for ignoring extreme values
• Advanced customization: Customize which measurements to display, report types to use, filters to apply and color schemes to present
• Comparison across load sessions: Easily compare two or more sessions in a single report
• Publishing: Print and publish into standard 3rd party formats such as HTML, PDF, RTF, CSV and XLS (Excel)
• Automation: Invoke WebLOAD Analytics using the extensive command line interface

Visual Studio 2010 Ultimate edition has the load testing funcationality. This helps in simulating realtime usage of the web applications. Different metrics can be captured from performance counters. Test thresholds can be set to identify if test has passed or failed. Yes you would need license for ultimate edition to use it. Though ultimate edition comes with complete developement kit along with testing.

Performance testing measures the time taken, the scalability and reliability of an action which is key to performance testing. Testing Anywhere allows testers to better create, manage, edit and analyze their performance tests. Advanced logs provide testers with details on each action, the entire test and even the performance times for a suite of tests.

• Quickly and easily expand and revise test cases and test suites as your requirements evolve and change.
• Immediately validate requirements and specifications.
• Extensive test coverage as your product is ported onto multiple operating systems, databases, and languages.

WAPT is a load, stress and performance testing tool for web sites and applications with web interface. You can test websites running on different environments and also test multilingual sites using different language encoding options. Accurate simulation of real user activity like different types of virtual users visiting different pages, automatically filling forms, clicking buttons and performing any other usual activity of real users. WAPT collects exhaustive information about web site behavior which is represented in form of descriptive reports and graphs.

HP LoadRunner allows you to prevent application performance problems by detecting bottlenecks before a new system or upgrade is deployed. It lets you deploy quality applications with confidence and enables consistent repeatable testing processes. HP LoadRunner helps you:

• Emulates production workloads
• Tests range of application types: rich internet, Web 2.0 and composite
• Identifies performance bottlenecks
• Diagnoses root cause issues
• Improves application performance before deployment
