Session & PHP & Joomla & Code Optimization

Question

I'm using Joomla 2.5.

1st method

JFactory::getSession()->set('mymessage', 'here is some message text');

2nd method

$session = JFactory::getSession();
$session->set('mymessage', 'here is some message text');

I use above methods(1 or 2) in my constructor. So I want to optimize the PHP code since it will be called multiple times during execution. What I want to know is which method is effective and efficient?

Thanks

Answer 1

对于每种方法（1和2），循环10次循环10 000次，并用微量时间计时并计算平均值。

Answer 2

First is un_named session variable call which will avoid $session need and initialization apart from that everything is same. therefore first may have some efficiency over space may be in time also.
