[QUOTE="berrill, post: 1170072, member: 33216"] I have just replaced my old 4 year old iMac with a new 27' 2.8 Ghz i5 I dont find this iMac much faster than my old one, in fact in some respects it seems slower, The hard drive seems to be constantly crunching away, and Activity Monitor reveals that a resource hungry programs like iMovie and iTunes are often not responding for periods of time. The Kernal_task is using about 10% of the cpu and about 140 meg of real memory, Is this correct are there any programs I can download to test the iMac, I have returned it to the dealer who reset the pram what ever that is. I have also deleted windows 7 on the bootcamp as I have read this can slow the iMac down. I cant believe that I see no speed improvement with an iMac what is 4 years younger. Any ideas how to find a potential fault. Regards Antony [/QUOTE]
