    Hey folks, had my laptop for a year now and just recently its taking a lot longer to boot up and windows longer to load.

    I think its fair to say it got a fair bit slower since upgrading to Lion actually.

    Im thinking on reformatting to get rid of some rubbish that may of built up, however I have also actively been backing up to Time Machine.

    I figure that if I reformat and install from my most recent TM Backup, will I just be back to square on, installing all of the rubbish on it again?

    So im wondering if its possible to reformat my laptop but only just my TM machine backup for certain things?

    For performance issues, there are a few things you can check:
    • Check your Login Items under System Preferences > Accounts to see what you have automatically launching.
    • Also check /Library/LaunchAgents/ and /Users/yourusername/Library/LaunchAgents/ for items launching at startup
    • Look at what widgets you may have running.
    • Launch Activity Monitor and change "My Processes" at the top to "All Processes". Then look to see what may be consuming system resources.
    • Take a look at the System Memory tab at the bottom of Activity Monitor to see if you have excessive "page outs", a sign that you may benefit from more RAM.
    • Make sure you're not running any 3rd party antivirus app, as many of those will drain resources, reducing performance. They're not needed to protect your Mac.
