I won't lie, I'm not very familiar with the super technical side of computers. That being said, I picked up an extra 4gigs from a great MR member here. Once I loaded it up (going from 4 to 8), i noticed the improvements IMMEDIATELY. But as I checked my activity monitor, while I have a good amount of free ram now, Im wondering if my "memory used" is larger than its supposed to be while having no programs open. When I had only 4gb's, my memory used would be around 3.87 with no programs open. Even just having itunes open would slow safari down to a crawl. Don't get me started with iPhoto. It would take a good 20 second for it to load. So even though I had a good amount of free ram now that I have 8g, Im wondering if there might be a kernal problem that is making my kernal_task so high?
