First, visitors depend on the Slickstream features added to the site for navigation. If search is delayed, for example, frequent return visitors who expect to find it may have to wait for it to load before being able to use it.
Second, Slickstream takes extreme care with its embed script to minimize the impact on site performance and load time. Only a few simple actions are loaded immediately. These are the actions necessary to ensure immediate key functionality for search boxes and buttons as well as favorite buttons. Slickstream then intentionally defers the remaining work to ensure only a negligible impact on loading. For example, if someone clicks on a search button immediately after loading the page, Slickstream ensures that it will not miss that click. However, after the click is captured, there may be a short delay while the full search functionality is loaded. This ensures a good User Experience with minimal performance impact.
