Today i decided to install a windows partition using bootcamp. At first I didnt give the partition enough memory so i deleted it and partitoned it once again. After going back to OSX i noticed a huge difference in performance. Everything ran incredibly slow and took a long time to process even the simplest tasks. Thinking it would solve the problem i once again deleted the windows partition. I rebooted and things got a little better. I then tried to repair disk permissions and again had little results. Whenever i have itunes open or try to open it, it causes big problems and everything slows down. The same thing happens anytime i try to play an audio file on any player. However if i keep itunes closed and don't try to play any music things run decently, still slow but decent. But in order for things to stay this way i have to constantly clean my RAM up. If i don't i get left with around 10 MB of RAM. I checked the activity monitor and seems that coreadiod is using up the RAM. The process is staying around 115% of CPU usage. This happens even when everything is closed and i am idle at my desktop. This is a big problem and i can never have more than about 3GB of RAM free and even then it quickly drops until i'm left with just MB's. My MAcBook is a 15 in. retina MBP with 8 GB of RAM. Before the bootcamp OSX always ran super fast with no problems. There is only one thing i can think of that caused this problem. In my windows partition i downloaded various media players including itunes and winamp. I was trying to basically share my itunes library on the OSX partition over to the windows. To do this i changed the itunes media folder location to the one on the OSX partition. This did not accomplish my task but it did keep that file directory. Also with windows media player i added the same itunes media folder to the list of folders for WMP to access, this also did not work. In winamp i added the same folder and it read my music no problem. I think this is where the problem lies seeing as itunes and playing audio files seems to leave my computer almost unfuctional. The odd part is it doesn't even have to be an audio file in my itunes library, a file completely seperate that i didnt try to add to the windows partition causes the same issue. I'm not too knowlwedgable on this so i have no idea what else to try. Any help or any suggestions as to what to do would be greatly appreciated. ---------- On startup everything works great until I try to open iTunes or play an audio file. itunes does not open and if I force close it, coreaudiod then starts to use up all of my RAM.
