First off I am running a 2010 15" MBP with the latest Snow Leopard. Sometimes when I login it is very fast and all my apps that open at login start very quickly (menu items mostly) and the computer is responsive and ready to use in a few seconds. However, other times it takes 30 seconds or more to become responsive (ie. loading icons, menu items etc.) and when I open safari (first thing I usually do) it takes a long time to open. Why this inconsistency? I tried taking a screenshot of activity monitor when I login but it took me a while to open it and most everything had loaded. I'll include it anyway. Is there anything I can do to make it consistently fast? It seems odd that it is sometimes slow for no apparent reason. Thank you.
