Back in the days before I learned about vim, Textmate was the choice for editing huge data files.
Didn't ever understand people who used it for the things Notepad++ could do back then though.
I usually try to keep my source files and config files smaller than a few hundred megabytes. Sounds like you might need more specialized tools for your unusual approach to editing source code.
