Also, something which is data i/o intensive is going to be the best case for a FUSE filesystem. If you try something which is much more metadata intensive (i.e., lots of file creates and deletes, chmods, etc.) like say with a Postmark benchmark, you would almost certainly get very different results. That's not to say that bonnie++ benchmarks aren't useful, but when doing comparisons between filesystems, it's a good idea to use a wide variety of benchmarks to avoid getting potentially misleading results. - Ted - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
