Should I do any rendering?

I have added code to my $w.onReady( function ().
I’ve added some code to make certain elements have effects when they load (eg spin)
And also some code to check if the current user is logged and whether they are in a current session. (My code is below)
My code all works but I want to know if I can make the loading quicker by adding manual rendering. (I am not sure if the quickest rendering process is happening anyway)

I read a bit about the rendering process, but not too sure how to proceed.
Any help would be much appreciated!

$w.onReady( function () {
let fadeOptions = {
“duration”: 1200,
“delay”: 0
};
let floatOptions = {
“duration”: 1200,
“delay”: 0,
“direction”: “bottom”
};
let spinOptions = {
“duration”: 2000,
“delay”: 0,
“direction”: “ccw”,
“cycles”: 10
};

$w('#winMessage').hide(); 
$w("#logo").show("spin", spinOptions); 
$w("#playNow").show("float", floatOptions); 
$w("#howToPlay").show("float", floatOptions); 
$w("#stars").show("fade", fadeOptions); 

$w.onReady( **function**  () { 

if (wixUsers.currentUser.loggedIn && !session.getItem(‘isLoggedInThisSession’)) {
wixLocation.to(‘/’);
return wixUsers.logout();
}

if (wixUsers.currentUser.loggedIn) {
session.setItem(‘isLoggedInThisSession’, ‘yes’);
let user = wixUsers.currentUser;
user.getEmail()
.then((email) => {
$w(‘#loginMessage’).text = email;
});
}
});
});

What exactly do you mean by manual rendering?

Also, your code example includes two onReady() functions which is invalid. Only one is allowed. The last one appearing in the code overwrites all previous occurences.
