Fragmentation won't hurt you that much, and it doesn't even apply to opens, since those operations are significantly smaller. The performance gains higher in the stack from a larger rsize/wsize generally outweigh the savings in frame size optimization. Of course, jumbo frames are always a good idea, but again, doesn't help here. -Aaron -- 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
