Ah, ok. This matches my own experience then. Sublime Text 2 is very fast for normal types of operations and file opens but I find that once something gets to be 10s of megabytes log, it has some serious issues. Granted, if you have single source code files that are 10s of megabytes long then you're generally doing something wrong, but for situations where you unavoidably do have very large files, Sublime Text kind of sucks at opening them compared to just about every other programming-focused editor I've ever used.

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).
