Hi folks (NB. The text below is not meant as a MP bashing thread - I'd really appreciate some advice or ideas!) So, I'm running a Hexacore MP 2010, with 24GB of OWC ram, 3x 2TB drives (Blue + 2 Blacks) software raided together, 1TB bootcamp drive (Green), 240GB Vertex 2 SSD, hooked up to a 27" cinema. The experience is woeful. I used to have my Dell 24" screen hooked up as a second monitor, but lately I've found that whenever that's in use everything on the screen and the mouse become very laggy. This morning it beachballed to death while I was moving some mail around. Safari barely works, and the whole system grinds to a halt if anything Flash/Silverlight plays. The machine never sleeps without pleasesleep... basically, I can't rely on it to be available when I need it. Sometimes on shutdown it'll just restart instead of turning off. I've tried formatting fresh, and this all still happening. So, some ideas:- - Could it be Parallels 7 (I'm just running a clean XP install though) - Perhaps go back to SL, and give up on iMessage etc - Don't browse the web?? - Could it be LogMeIn? - Go to Windows 7, which is very stable on the box, and sleeps properly - Reset the PRAM? The machine is a household server, running things like AirVideo etc. While I DO use it for work, I normally work in the office, so it's mostly used for personal projects. If you're interested in what I have installed, here's a snapshot: http://d.pr/YXQu Overall, a very frustrating experience. I have a MBA 2011 11", and it's an order of magnitude more stable. Thanks MR crowd.
