Chapter 10 Achieving Optimum Performance with PowerDynamo

Designing your Web site

When you create a dynamic Web application site, you should plan and design the site to provide optimum performance. A Web site can work only as fast as its design allows.

You should consider these factors when designing a dynamic Web site:

What is the expected volume to be hitting the Web site?
How often will the data being queried change?
What can you afford to set your cache size to?
How essential is the timing of the information being delivered? For example, does the data need to be updated every minute or is once an hour sufficient?

Once you have evaluated these factors you can decide how to best optimize your Web site. For example, if you are creating a dynamic Web site with high volume throughput, you'd probably want to take these steps:

Set the proper CachedOutputTimeout value.
Set a maximum cache size.
Schedule documents that can be.
Create the proper type of connection for each query.
Queries should be as specific as possible to support caching.

The following sections describe in more detail the features that are available to optimize PowerDynamo to its greatest possible performance.
