One thing to note with a lot of the lower end network chips is that you end up needing to specify rsize and wsize so that you don't get fragmentation - about 1k tends to work well IME. Otherwise performance often degrades to the point of unusability. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
