    I downloaded OS X Lion to my MacBook (2010) four or five days ago and ever since then, everything has slowed down. I almost always have to force quit applications, scrolling is slow, and just simple things like switching tabs on safari take more than a minute. Is there anything I can do to fix this issue?

    How much RAM you Macbook have? 4GB is the new minimum recommended.

    A clean install of Lion did not help my machine.

    Going back to Snow Leopard did.

    The thing that was slowing down my MacBook in Lion was Safari. There's a memory leak and the amount of RAM Safari was using would creep up the longer I had it open. It even reached 1.3GB of RAM at one point and I only had 3 tabs open!

    I switched to the WebKit nightly builds, but it had the same issue too, until this most recent build (which I haven't seen the amount of RAM gobbling that I have in the past). Also, Firefox 6 Beta is freakin' fast in Lion with no memory leak issues

    You think 1.3GBs is bad, try 5.71GBs with 2 tabs on bestbuy's website. It actually reached over 6GBs before I forced quit the program. Haha

    I've had the same problem with my 2GB Mac mini. Everything in general is slower than with SL.

    I never thought I'd see the day when Safari's memory leaks surpassed those of Firefox. I feel like the new Safari has taken a lot of cues from Mobile Safari, I've had that suck down over 100 MB on my iPhone 4 with just a few tabs open. Lion's Safari also seems to want to refresh non-focused tabs automatically, probably where a lot of that memory is going.

    I'll definitely be looking into the Firefox beta until Apple releases a Safari update. Thanks for the tip!
