I wasn't trying to say XFS fixes your problem, but that we could implement appending AIO writes in XFS fairly easily. To verify Jan's theory, can you try to preallocate the file to the full size and then run the benchmark by doing a: # fallocate -l <size> <filename> and then run it? If that's indeed the issue I'd be happy to implement the "real aio" append support for you as well. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
