That page is generated by function redirect_header in include/functions.php.
It wouldn't be practical to remove that page completely, since it often displays important information.
If you want to override the time delay, you could do so by adding a line at the beginning of the function, to force a particular value for $time (delay in seconds):
function redirect_header($url, $time = 3, $message = '', $addredirect = true)
{
[color=ff0000]$time = 2;[/color]
