4. Executive Summary
xDesign Online Editor enables business users to easily edit correspondence
interactively without the need to install and maintain traditional desktop software or
plug-ins. With the browser-based WYSIWYG interface, users can edit existing content,
add optional content, and protect content from unauthorized changes. The xDesign
Online Editor is a full-service editor, with comprehensive style and formatting
capabilities, spell check, and form-field support.
This report benchmarks the performance of the xDesign Online Editor and its web
services APIs. It provides performance data for editing a document, publishing a
document, returning it to the calling application or browser, and displaying it in the
user’s queue.
Test Method
The tests conducted simulate a production environment in which users are sending
simultaneous web service requests to the xPression server. Test results are shown for
1, 10, 50, and 100 concurrent requests. Testing was performed with Apache JMeter, a
graphical desktop application used to load test functional behavior and measure
performance.
Keep in mind, the number of concurrent users is not the same as the total user
population. For example, if you had 1000 users and 10 percent issue requests
simultaneously, this would match the test simulating 100 concurrent requests. During
a test, to simulate a constant load on the server for the appropriate number of
concurrent requests, the completion of one request triggers a new request.
The volume of concurrent requests will vary based on the number of users and their
use of the system, including how many documents they produce per hour and the
number of web services requests that are needed to generate a document. For
example, 100 users will produce 1,500 documents per hour if one user can process
15 documents per hour (1 document every 4 minutes). If each document requires one
to three web service calls (a reasonable estimate), that activity would create 1,500 to
4,500 web service calls per hour.

Performance Data
For each web service method, two sets of test data are displayed: Beneficiary Letter
and Auto Policy document. The column heading “Response Time (90%)” means that
90 percent of the requests were processed at or below the indicated elapsed time.
Method: createDocumentItem
The createDocumentItem web service method creates a document work item in
xPression. A document work item is a version of an assembled document that can be
revised before publishing.

8. Method: documentItemsAssignedToUser
The documentItemsAssignedToUser method (100 items for each request)
returns a list of document item IDs for document items assigned to a user. It can
return information about these document items through a subsequent web service
call, which uses the document item IDs as input into the documentItemInfo method.

Conclusion
Organizations that support call center agents and others who need to handle a large
volume of incoming calls face a number of challenges. They require a document
editing solution that offers fast document loading and editing performance.
Companies supporting these solutions require software that allows them to host
large, concurrent user populations in high volume environments, preferably from a
single server in order to keep costs low.
Until now, online editors, despite the attractions of simplicity and ease-of-use, could
not consistently deliver the necessary performance, especially with documents
featuring complex logic. As the results in this report demonstrate, xDesign Online
Editor has overcome these limitations. xDesign Online Editor meets the needs of
users for flexibility and control, and performs reliably under the demands of high
volume, high concurrency production.
