Thank you. I tried the suggestion (001.vmware.sh stop, which did get both
drivers out of promiscuous mode), and it gave an improvement, but it was
strange. Instead of the ~500KB/s downstream I got anywhere from ~500KB/s
to ~1500KB/s. I noticed that the more I downloaded, the more it would fall
to ~500KB/s and would then hover there.
Your suggestion got me to wonder if some other thing may not be unloading
when running 001.vmware.sh stop. And I noticed that the bridge kernel
modules were not unloaded, and would not unload manually if using kldunload.
Without going into further detail, I found if you just don't use bridging
at all, downstream will be the correct speed. So I changed to Host-Only
and put in a NAT and whalla no problems.(typical 6-7MB/s):)
I still wonder what the cause of the slow downstream in the bridging
was. Either way, this is a better solution since I now have easier control
of my Windows machine's network resources.
Thanks for all your help!
