Done. Host: Mandriva Linux 2010, x64, Intel Core 2 Q6600, VBox 3.2.0 + Qemu 0.11.0 Guest(s): RHEL 5, x64 Qemu/KVM used as part of Mandriva 2010 distro. ============================================= Test between Host <-> Guest: -- Qemu/KVM vs VirtualBox ============================================= VirtualBox: Connection via VBox "Bridge": (guest has VirtIO, connected to host's eth0) 270-280 Mbit/sec Connection via VBox "Bridge": (guest has E1000, PRO1000/MT,, connected to host's eth0) 136-143 Mbit/sec Qemu/KVM: Connection via KVM "Bridge/TAP": (guest has VirtIO, connected to host's tap0) 1.06-1.12 Gbit/sec +400% speed advantage Connection via KVM "Bridge/TAP": (guest has E1000, PRO1000/MT, connected to host's tap0) 185-188 Mbit/sec +30% speed advantage I don't know if the performance would be highter with TUN/TAP (VBox 2.0 and older) mode... i.e. Is the slowdown causes by vboxnetflt or some other reason ? Unfortunately VBox 3.2.0 does not support TUN/TAP, and VBox 2.0 won't install on such new hosts. -- -"Technologov" _______________________________________________ vbox-dev mailing list [email protected] http://vbox.innotek.de/mailman/listinfo/vbox-dev
