Overview

If you anticipate anything more than a handful of readers subscribing to your channel, you should definitely consider setting up caching for your channel's pages.

Caching can significantly reduce the time it takes your readers to download your channel when they sync. The higher the volume of channel traffic — number of subscribers times size of channel — the greater the reduction in download time that caching can potentially provide.

If you are not sure that caching is worth the trouble, be sure to read Introduction to caching. Substitute your own projections for the numbers of downloads you expect on your channel. Unless you expect a very small number of subscribers, you will probably conclude that caching is worth the trouble!

Note: If you do decide to implement caching, wait until you are finished testing your channel to set it up. Why then is this chapter not placed at the end? Because many of the tips and tricks in the following chapters mention caching; if you were reading this guide straight through, this is the logical place for this information to appear.

If you are really in a hurry to get your channel up and running, you can skip this chapter until you run into caching in the discussion of one of the other tips and tricks — or until you are ready to make your channel available to the public.
