Ensure the quality of

enterprise applications under

dynamic load conditions

During enterprise application development,

SilkPerformer helps you answer critical questions,

such as:

■ How can I optimize my multi-user application before it goes live?

■ How can I detect errors that only occur under real-world conditions—before deployment?

■ Where are the bottlenecks in my multi-tier environment?

■ What system capacity is required to handle the anticipated load?

■ Will my users experience acceptable response times, even during hours of peak usage?

■ Will my application meet the response time requirements of my customers?

Ensure the scalability, performance, andreliability of your enterprise applicationsSilkPerformer ensures the quality of your

enterprise applications by measuring their

performance from the end-user perspective, as well

as internally, in a variety of scenarios under

dynamic load conditions.

Using its innovative TrueScale™ technology,

SilkPerformer can simulate thousands of concurrent

users with a single computer—providing you with

the power required for visual content verification

while consuming a minimum of hardware

resources. When required, load test agents located

at remote test centers can be utilized without com-

promising firewall integrity. Within a single load

test, virtual users working with different Web,

middleware, and database protocols—in addition to

varied computing environments—can be simulated.

Client IP address simulation allows for the testing of

load-balanced sites. Support for the latest Internet

security standards also enables SilkPerformer to test

all aspects of your mission critical enterprise appli-

cation. SilkPerformer’s Benchmark Description

Language (BDL) is specifically designed for testing

purposes and provides an easy and powerful means

of controlling user activity.

Web pages are accurately requested by emulating

the connection behavior, cookie management, and

caching strategies of real browsers. Meanwhile

TrueModem™ technology and realistic workload

models complement SilkPerformer’s unmatched

accuracy. Finally, verification under load ensures

that functional errors such as incorrect Web

page content are detected reliably—under all load

conditions.

Plus, industry-standard interfaces for extensibility

ensure that SilkPerformer can be used in scenarios

SilkPerformer® is the industry's most powerful—yet easiest to use—enterprise-class load and

stress testing tool. Visual script generation techniques and the ability to test multiple application

environments with thousands of concurrent users allow you to thoroughly test your enterprise

applications’reliability, performance, and scalability before they are deployed—regardless of their

size and complexity. Powerful root cause analysis tools and management reports help you isolate

problems and make quick decisions—thereby minimizing test cycles and accelerating your time

to market.

for which out-of-the-box functionality is not

sufficient.

Test remote components early in the development cycleDramatically reduce the cost of bugs in your multi-

tier enterprise application by testing the function-

ality, interoperability, and performance of remote

components under concurrent access early in the

development cycle—even before client applications

have been built. You can rapidly generate test driv-

ers for Web services, .NET remoting objects, EJB’s

and Java RMI objects by exploring them via a

point & click interface. Alternately, you can reuse

unit test drivers written by developers for concur-

rency tests or you can build new test cases directly

in Java and other .NET languages, such as C# and

VB.NET, using SilkPerformer’s Java Editor and

Visual Studio .NET Add-In.

Create test scenarios quickly and shortentest cycles■ Use SilkPerformer’s Integrated Test Environment as

your single point of control

■ Set up and configure large load test environments, including multiple agent computers, in minutes—all from a single location

■ Discover SilkPerformer’s ease-of-use with its built-in methodology based step-by-step workflow wizards

■ Automatically generate scripts that include content verifications and JavaScript handling—virtually eliminating the need for manual scripting

■ Easily customize tests with random user-data without programming a single line of code

■ Reuse test cases in different environments and scenarios without changing test scripts

■ Quickly create realistic workloads by using SilkPerformer’s integrated workload wizard

■ Automatically balance loads across all agent machines driving load tests

■ View your load test health in real time—thereby avoiding invalid test results that require time-intensive test case re-runs

Pinpoint problems easily for quick resolutionSilkPerformer’s unrivaled TrueLog™ technology

for HTML, XML, SQL, TCP/IP, and UDP based

protocol data provides full visual root-cause

analysis from the end-user perspective. TrueLogs

visually recreate the data that users provide and

receive during load tests—for HTML pages this

includes all embedded objects—enabling you to

visually analyze the behavior of your application

as errors occur during load tests. Plus, detailed

response timer statistics help you uncover the

root causes of missed service levels before your

application goes live.

With the addition of the Server Analysis

Module™, you can monitor server statistics and

correlate data with load test results to identify

ongoing problems with your system’s back-end

servers—even when servers are located behind

firewalls.

Ultimately, SilkPerformer’s Web-based manage-

ment reports are easy to share, customize, and

understand which enables non-technical decision

makers to quickly interpret test results—thereby

saving time.
