Overview
Whether you distribute your enterprise reports over a local network, a
corporate Intranet, or the Web, you can use Crystal Reports' powerful, built-in
performance features to deliver web reporting speed.
Crystal Reports automatically provides these major performance
advantages—even if you don't apply any of the strategies set out in this
section:
• Page-on-demand technology
Page-on-demand report access lets users download only the specific
report pages they need to see, thus improving response times and
reducing web traffic. Further, placeholders and partial page technology
allow you to view report pages and data over the Web immediately, without
having to wait for the processing of large objects, such as graphics and
subreports.
• Optimized, multithreaded Report Engine
The Crystal Report Engine's multithreading capabilities and thread-safe
database drivers allow you to continue working on your important tasks,
while many other operations are processed simultaneously in the
background. The Report Engine also minimizes the number of passes
made through the data, speeds up processing with improved memory
management, and handles subreports and parameters as efficiently as
possible.
In addition to these built-in features, the Key strategies for optimizing web
reports discussed in the following sections bring additional performance
benefits, which are often substantial. When you design new reports (or
improve reports created in older versions of Crystal Reports) in accordance
with these strategies, reports run faster and tie up fewer processing
resources. Consequently, report users can easily access the data they
need—faster than ever.
Tip:
If you're new to web reporting, or to reporting in general, reading this section
will prepare you for future reporting tasks—you'll gain important insight into
designing faster, better reports.
