How to avoid syntax-highlighting for large files in vim?

Question

Huge files take forever to load and work with in vim, due to syntax-highlighting.

I'm looking for a way to limit size of highlighted files, such that files larger than (say) 10MB will be colorless.

Answer 1

Adding the following line to _vimrc does the trick, with a bonus: it handles gzipped files, too (which is a common case with huge files):

autocmd BufWinEnter * if line2byte(line("$") + 1) > 1000000 | syntax clear | endif
