Does Lion/Safari "learn" after the update? Reason I ask is because immediately after the update Safari felt slower but the longer/more I use it the faster it's continually getting. iTunes is now faster as well. Right after the Lion upgrade I would click the button to open iTunes, there was a delay, iTunes opens and the menu down the left side is showing but there's nothing in the song list. There's a 4-5 second pinwheel and then everything shows up. After opening and closing iTunes several times it now launches instantly. However, I'm still getting the slowness in iPhoto. I launch iPhoto and everything opens and my pics are displayed but you can't click any of the menu bar buttons at the top for several seconds and then all of a sudden it works.
