WordPress site will slow because of sessions in some cases

Yes some times WordPress will slow because of sessions

In some cases we have started session in functions.php and header.php.

When we place session_start() in header.php site will slow down at that time we need to use cookies like below

Set cookie 

<?php setcookie(“CookieData”, $value, time() + (86400 * 30), “/”);  ?>

Get cookie

<?php echo $_COOKIE[“CookieData”]; ?>
