I have: CPU: Intel Core i7-860 (Quad core) 2.8 GHz Mobo: Gigabyte: GA-P55-UD3P P55 1156 pin DDR3 RAM: Patriot Signature 4GB 2 Ghannel Kit DDR3 1333 (for Intel 775 pin, Intel p55, AM3) The set-up is about 1 year old & my 2TB HD rarely shows defrag at worse than 0.5%, most partitions are 0.0%. On the whole I consider my computing is slow. Slow to load, slow to wake up, slow to launch programs, & slow to shut down. What infuriates me is that only very rarely do I see CPU utilisation higher than 20%, & then it's usually around 37% doing flat out file copying. Also very frequently below10%. I have a couple of widgets providing this info: Core Temp reports RAM usage. CPU Usage shows the utilisation average & with each of 8 "cores". As I write now I observe the RAM usage at between 40 & 60% while the CPU usage is only 12%. Simultaneously TaskManager shows 00 CPU usage for all running processes. Can anyone offer some explanation (I'd be happy to run any recommended benchmark tests) or what I might do to sort this out. I can remember when my first Pentium II processor seemed just as fast although that rapidly lost speed.
