It looks fine. Hmmm.... What version of linux do you use?
Congestion avoidance mechanism of NFS clients might cause this situation. I think the congestion window size is not enough for high end machines. You can make the window be larger as a test. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
