Hello, In the past, I used my PC to import my CDs to iTunes. I achieved 14-16X with that 2.4 GHz processor. With my new 17" 1.83 Intel Duo, I can only get 5-6X. I know that if iTunes would use only 1 CPU, then it would be slower than my P4, but not by 2/3. Is this a known issue? Is there a setting to adjust this? Thanks!
