Quad Core subjectively slower on some tasks
Am just getting around to tackling this having upgraded my old machine from an Athlon XP 3200 (2.2GHz) and an Intel i7 2.66GHz overclocked to 3.2GHz.
There is no doubting that this processor runs stuff like Photoshop CS2 and Lightroom etc much faster, just how they should be. My old Athlon used to struggle.
However, with everyday computing tasks there can be noticable lag. Examples are opening an excel spreadsheet, opening Outlook, add/remove programs population, applying changes to display settings etc. All usually just okay but not quite as instant as my old Athlon. There can be processing delays with basic tasks that just were not present with the Athlon. Task manager never really shows much activity. In fact I have never seen any core above 17% with the i7. These issues are always worse at start up when I can see disk activity but I am not sure what is going on.
I have been experimenting with Windows Desktop search which was certainly implicated. I have uninstalled this. I have also changed the settings on my backup application (Mirror folder) so that it does not run whilst the machine is starting up. These have definitely improved the situation but I still don't see much if nay improvement with these basic tasks.
Maybe I am just running into a hard disk bottleneck....?
Can anyone shed any light for me on what I am seeing?
