- Once you have installed the tool, simply run it by pressing the 'Record' button the first time. This will then capture all http requests on your browser on any sample application. Finish recording and save the script. Then point the 'server' field in the tool to your server fully qualified host name and press the Play button.
- In the past, I used Microsoft Web Application Stress Tool and Pylot to stress test web applications. I'd written a simple home page, login script, and site walkthrough (in an ecommerce site adding a few items to a cart and checkout). Just hitting the homepage hard with a handful of developers would almost always locate a major problem.
Introduction Microsoft Web Capacity Analysis Tool (WCAT) is a free lightweight HTTP load generation tool, part of IIS 6.0 Resource toolkit that is used to test performance and scalability of IIS and ASP.NET application. This tool is used internally by IIS team and NT Performance team use to conduct internal performance and scalability testing.

Loadtracer is an effective performance testing tool for web application
Load, stress, scalability, capacity, volume and endurance can be done effectively using LoadTracer.
It is the unique tool fully developed from testing perspective.Loadtracer is very effective Load Testing tool for web application at affordable price
Testing is done in three phases. One is recording the script using RECORDER, Simulating with hundreds of virtual clients using SIMULATOR and then analysing the result using ANALYZER.
During performance testing, all the performance measurements can be logged using performance counters effectively to determine the performance issues and bottlenecks in the web application. which is further used with analyzer to generate graphs, reports which can be exported into different formats.
The load tracer was developed in C language and hence the size of the tool is very less. It interacts directly to OS using various techniques to create virtual users as real users. parameterization is used to generate the data dynamically and distribute unique data for each and every virtual user. Sharp load is being generated on the server. This results in getting high accuracy in hits per second and sharp concurrency compared to other load testing tool available in the market.
RECORDER
Recorder acts as a proxy server between browser and the web server. It records all the interaction between browser and server to generate script file. The scripts are automatically generated. No need to write scripts.
SIMULATOR
Simulator uses script file to generate hundreds of virtual users to hit the server concurrently or sequentially. Different options are given to modify the scripts. Independent settings can be done for each script.
ANALYZER
Analyzer produces many types of graph and reports for analysis purpose. All the performance logs collected through LTMonitor are analysed through Analyzer. Many types of report and graphs can be generated in HTML and CSV format
LT MONITOR
LT monitor provides variety of performance counters to monitor. Necessary performance measurements can be logged to determine the performance issues and bottlenecks in the web application.
List of features are given aliging with the phase of performance / load / stress testing

Recorder acts as a proxy server between browser and the web server. It records all the interaction between browser and server to generate script file.
It records all the request and response from the client and server and generates script.
The script is corrected and parameterised as per the requirement using various options given in recorder. Many types of functions are available for parameterization, Variable Management, and Response Validation.
During this recording session itself, the RECORDER generates a detailed report for different parameters like request time, response time, number of bytes sent and number of bytes received.
In Many web application http errors are customized, so it is hard to find in runtime whether a http exception has occurred or not, using response validation with different methods we can determine whether the response is valid or not.
In SIMULATOR, the recorded script in RECORDER is used for simulating the virtual client. The number of clients and the other parameters like think time, iteration, proxy settings, cookie usage, etc., can be specified in SIMULATOR setting based on the requirement.
By executing the script, SIMULATOR hits the server with the specified number of virtual users based on the requirements.
Each virtual users will run on a separate thread and carrying its own data and other parameter simulating real user environment.
Using vuser scheduler, load can be released in ramp up and ramp down manner for specified amount of time to simulate realtime load.
The result of all virtual users are stored in separate file.
These raw data is sent to ANALYZER. SIMULATOR also sends its data to Analyzer
The ANALYZER will analyze the virtual users data and generate a detailed report.
There are many type of graph for example running virtual user or active virtual users, hit per sec, response per sec, bytes send per sec, bytes receive per sec, number of text files downloaded per sec, number of binary files downloaded per sec,.
Two important features provided by Analyzer is Detail Information By Virtual User and Detail Information By Files. These features provide very minute details like time taken to complete a request, time taken to complete a response, number of bytes send, number of bytes received, content type of response, HTTP status codes.
The report can be generated in many formats like tabular, graphical.Results can be published as HTML pages or excel pages. All the reports are stored in html pages. These reports can be exported HTML format.

Using loadtracer, TRACE offers wide range of testing services also. Key testing to know about the exact behaviour of your web application
Hard Drive Stress Test Tool
Performance testing is not just to determine response time and throughput but it is also to determine the various performance attributes like bottlenecks ( memory, disk, process, processor, cache, network, etc.) and resources leakages is present in normal scenario.
Loadtesting is to determine the risk factors associated with increasing the load on the application. And to determine the performance behavior of the system under load. And it is also evaluate the compliance of a system or component with specified load requirements.
Stress testing is not just to determine stress point (when the system goes down or crashes because of increase in load) but also to determine the factors affecting the stress point. It also to determine the performance behavior of the system causing stress point.
Scalability testing is to determine system behavior by increasing the load with a various scaling ratio. For every scaling point all the performance attributes have to be determined. Also the factors affecting the application scaling capacity have to be determined.
Capacity planning is to determine the optimum capacity needed to address the IT infrastructure needed for production requirements. It is all about mapping the correnct hardware, software and network requirements to determine the capacity bottlenecks.
Volume testing is to determine the system behavior with increase in volume of data. Large volume of data has to be applied to the server in scalable manner over a period of time. The volume factors affecting the application’s performance have to be identified.
LoadTracer has three modules RECORDER, SIMULATOR AND ANALYZER
- LOADTRACER - RECORDER : Records the scripts
- LOADTRACER - SIMULATOR : Simulates virtual users based on recorded scripts
- LOADTRACER - ANALYZER : Review and export result output from simulator.
