i'v been kind of frustrated with lion's memory. i have 8GB but i still run out of memory... i use the 'purge' app which frees up the memory, but honestly, this is unacceptable way to experience the use of a computer. im tired of having to go and use these feautre and have my system lock up for a moment, its a clunky operation to do. so im hoping someone can help me - is this really my apps that i'v installed causing this problem? or is it lion? iv read differing arguments about this. i don't know what to conclude? if it isn't lion, then what apps are known for causing this? i regularly use the following apps: App Store Mail Address Book iCal iPhoto iTunes iMovie Skype Dropbox i want to figure out what could be causing this memory leak? i use photoshop often as well working with some veyr large files, but is photoshop known for leaking memory? is there any app out there which can help me figure out and tell me whats causing my memory leaks?
