Hi, Does anybody know whether the ring buffer between front end and back end will suffer from overflow? I just wonder if the ring buffer will be full and drop some packets when the Net I/O load is very heavy. BTW, If I want to change the size of i/o ring buffer, how should I do? I tried to reset the NET_TX_RING_SIZE and NET_RX_RING_SIZE in both front end and back end, but it seems doesn't work. Thanks. Regards, Cong _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
