Performance considerations

The extension fetches banners asynchronously from the webserver where the TYPO3 installation resides. Since the plugin has to count the impressions for each banner on every page-impression, the plugin runs uncached. I’ve implemented the TYPO3 Caching Framework to face this problem, so the HTML output for the banners do not have to be rendered on every page request.

To keep the performance of the extension at a reliable level, you must keep in mind, that using the plugin multiple times on a page will result in multiple asynchronous requests to the uncached plugin. This will reduce website performance on high traffic sites.
