Performance

Publisher does a lot of things. It is a large add-on that brings a massive feature set, therefore, it will add to the page load time of your sites. It is difficult to say exactly how much time it will add because it depends on what features you are using and what 3rd party add-ons you have installed. For this reason, it is recommended that you have some sort of caching strategy for your site (even if you are not using ExpressionEngine or Publisher, you should have some level of site caching). Fortunately, we also offer a fully featured caching module called Speedy. Publisher has a lot of built in caching as well. For example, the first page load after saving an entry may take additional processing time and queries because it will be re-generating some caches.

Publisher 3.x comes with built in bench marking. If you have the Output Profiler enabled on your site. Below is an example of the bench marking output added to ExpressionEngine's Performance tab in the Output Profiler. As you can see you in this example, the full page took 14 seconds to create an un-cached page, but only 3.2 seconds of it is the result of Publisher's hook calls and other processing.
