I have one question related to Magento new version its good for security point of view and other point which is mentioned there release note but there is no much enhacement related to front end performance.
Currently i have Magento 1.4.2 on my ongoing project for which client complain me performance are slow for end user prespective, to overcome this issue i tried to test Magento 1.8 performance for similar test cases but i don't even find any performance boosting result like in category page i get same loaing time in both Magento 1.4 and Magento 1.8 and also when i import 10,000 product and then check performance for loading time but there is no effect.
can any one highlight Why Magento 1.8 is better than Magento 1.4 it obviously newer version is better than old but i want to convience my client with some convincible point.
Thank You
