Hi, I'm in the middle of writing a network driver for Solaris 10 to use a VirtIO backend. I've gotten the basics working and throughput between two VMs on the same host is ~ 4x faster then when using the rtls interface. When I'm looking for is some guidance as to which of the features (CSUM,MRG_RXBUF ,HOST_TSO,GUEST_TSO) give the "most bang for buck", i.e. which should I look at implementing first Thanks, Conor -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
