Keynote Demonstrates Next Generation Web Performance Test and Measurement Products for Web Developers at Web 2.0 Expo

-- First Public Demonstration of the Keynote Internet Testing
Environment (KITE) at Web 2.0 Expo

-- Keynote Bridges the Gap Between Web Developers, QA Testers and
IT Operations

-- KITE Provides a New Desktop-Based Test and Measurement
Environment for Recording, Editing and Analyzing the
Performance of Sites Using Web 2.0 Technologies
SAN FRANCISCO--(Business Wire)--
Keynote Systems (Nasdaq:KEYN), the global leader in on-demand
mobile and Internet test & measurement solutions for continuously
improving the online experience, demonstrates today the company's two
flagship Web application performance test and measurement product
offerings -- Transaction Perspective(R), Application Perspective(R) --
and for the first time, the company's newest product, Keynote Internet
Testing Environment (KITE) at Web 2.0 Expo, Booth 300, April 23-25.

"In keeping with the spirit of Web 2.0 Expo's "unconference,"
Keynote invites Web developers and QA testers to visit its booth and
see the first public demonstration of KITE and interact with our
products team on the future of Web 2.0 application testing and
performance monitoring tools," said Vik Chaudhary, vice president of
product management and corporate development at Keynote.

KITE enables Web developers and QA professionals to execute rapid
performance analysis and validation from their desktop or Internet
cloud to measure the end user experience of next generation Web 2.0
applications that include AJAX and asynchronously downloaded content
with point and click ease. KITE bridges the gap between Web
developers, QA testers and Web operations teams by embedding a version
of Transaction Perspective and Application Perspective measurement
software within the environment; the very same software that drives
Keynote's globally distributed network of measurement computers.

Keynote Transaction Perspective is the most accurate Web
application performance measurement product on the market and utilizes
an actual browser as the playback engine to measure and benchmark the
end-to-end performance and availability of Web 2.0 applications
including Rich Internet Applications (RIAs).

Application Perspective is a software-as-a-service and root cause
diagnostics product for online applications that provides advanced
emulated multi-browser support (e.g., Firefox, Safari, Camino, Opera),
the ability to precisely measure response times and availability
issues of complex Web sites by interpreting and executing JavaScript
elements and enhanced parsing of Cascading Style Sheets (CSS), as well
as HTML and header capture, which assists the user with a visual
diagnosis in the event of an error.

"In today's increasingly complex Web environment, companies are
recognizing both the value and need for consistent Web monitoring and
testing tools that are as advanced as the technologies they test,"
said Lisa Erickson-Harris, research director, Enterprise Management
Associates (EMA). "As companies grow increasingly dependent on their
online presence, a single testing and measurement platform that allows
developers to instantly test and measure the end user experience of
Web 2.0 applications is a significant advance that supports today's
demanding and complex environment."

Whether a customer is looking for high accuracy for competitive
Web application benchmarking, a desktop-based rapid performance
analysis tool or high frequency operational monitoring, Keynote offers
a product/solution at the right price for all the applications a

Web applications, to highly interactive Web 2.0 applications that use
