I've not heard of any data integrity issues with using barriers on EXT3. But, it might not provide a performance boost, depending on the size of your files. According to some research I did, writing a lot of 10K or less files will be slower than with barriers off. I _have_ been hearing of problems with file systems being remounted read-only when barriers are turned on, and some sort of temporary disk error happens. We'll be putting out an updated ext3 driver to hopefully correct that problem.
