Our servers normally respond between 80 to 300 milliseconds, hence blocking should occur fairly instantaneously.
If it is taking longer than this to block, then there is an issue with the code placement in your website.
For the fastest block, our code should be the first to process in your website and should not be slowed down by any other external scripts or files present in your website.
Ensure our block code script is placed just after the opening head tag in your website.
<head>
-- Our block code should be the first --
-- All other scripts in the header should be placed after our script --
