Hi guys, I have a 27" mid-2010 iMac 8GB 1TB HD on SL 10.6.8 running in what seems to be really slow process. Trying to run Photoshop and just a simple web browser in the background seems to 'hog' the machine. Do you know what can be done to speed it up? Will updating to Lion on this machine help at all, along with an speed increase at all? Have you found Lion quicker to use on this machine?
