vim c mode bug?
Recently, I found that when you edit C programs using Vim, and if there are some big files (e.g. 500M) in the same directory as that C program, it's very very very very slow to save that C file (using :w), but if you move that big files to other directories, the saving process is done quickly as usual.
This problem doesn't occur when editing files of other types like perl, or plain text.
My system is Ubuntu 9.04, and my vim version is 7.2.
Any ideas? Thanks!
