I've got a 13inch Macbook Air and I love it, it is the best Mac I've ever owned, hands down. But there´s just one thing I don't like about it. When I unplug it and it sleeps for over one hour it goes into hibernation mode. But when I wake it from hibernation, depending on how many programs I was running, the memory swap files are filled and the computer is slow, it even lags when using exposé&spaces and other simple tasks. It wears off after a while, but it never feels as fast as usual until I reboot it. I get that this has to do with how the Air distributes memory or something along those lines but I would like to know more about it. Could someone knowledgeable explain in laymans terms why it happens? Could I avoid it by switching sleepmode in the terminal? I don't recall my older Macbook Pro's doing this.
