When you say "VMware does not have to be running", I assume you mean a virtual machine is not running. VMWare puts your interface in promiscuous mode. IIRC, the interface remains in promiscuous mode even when VMWare is not running (unless you stop disable vmnet or use ifconfig -promisc to disable promiscuous mode on your interface). I'm wondering if for some reason promiscuous mode is affecting your speed. What happens if you exit out of a VMware virtual machine and then run the following command: # /usr/local/etc/rc.d/001.vmware.sh stop Does your performance improve? If not, check to make sure the interface is no longer in promiscuous mode (look for the word "PROMISC" in the first line of output when you run "ifconfig vr0"). You can manually disable promiscuous mode by running the following command: # ifconfig vr0 -promisc What is vr0 plugged into (hub or switch? brand?)? > > My first reaction is this is unavoidable due to the kernel settings > required for vmware to work, but because everything works OK upstream, > perhaps I have set something up improperly? > > The only other thing I noticed was that I can't set debug.mpsafenet=0, > as it is readonly.
