I have also found Sublime Text 3 to be much faster at common tasks than Sublime Text 2. It is going to be well worth the upgrade.
Really? Can you define large and define instantly? Because the one thing Sublime Text 2 really sucks at is opening large files, in my experience.
ST3 is better than ST2 in this area, but still noticeably slower than any other "programmer" editor I use.
I do like the program a lot, this is one of my few complaints (the other major one being that there's no ARM/Linux version).
