If you are using the Smart Data Protector, then there are some extra steps that you may improve your performance. You can add the following <link> tags to preconnect and preload the uc-block.bundle.js script, increasing the performance:
<link rel="preconnect" href="//privacy-proxy.usercentrics.eu">
<link rel="preload" href="//privacy-proxy.usercentrics.eu/latest/uc-block.bundle.js" as="script">We advise adding two extra prefetch <link> tags for optimal performance:
<link rel="dns-prefetch" href="//app.usercentrics.eu" />
<link rel="dns-prefetch" href="//api.usercentrics.eu" />
