For the past 2-3 days, my computer has been lagging enormously. I cannot explain why this is the case - usually I have 50+ tabs open in Chrome, Colloquy, iTunes and a handful of other apps running at the same time, with little trouble (on a 1.7ghz 4gb 256gb 13" 2011 MBA). I have checked my memory and disk usage - I have over 700mb ram left, and almost 30gb of disk space. CPU usage is absolutely minimal, and there aren't any external displays connected.
What I've noticed is that many apps are performing with a significant lag when typing and scrolling - it sometimes gets to the point where I cannot type a sentence without the 'other letters' menu popping up (accents and symbols menu). Scrolling is also usually quite smooth, but now it's really botchy. I also tried playing a 1080p movie in VLC (which usually plays flawlessly), and it just kept dropping frames like it's 2006.
What have I done to remedy this? I have restarted the computer, I have closed all chrome tabs that I do not absolutely need, and ended the process of all tabs I currently wasn't using. I do not recall changing any critical aspects of the OS since the start of this nonsense.
