I have ~100 FreeBSD 8/9 VMs in my vSphere 5.1 environment, all using the
VMware tools package from VMware. Everything has been running great for
years.
(we skipped vSphere 5.0). Why should I use this vmxnet driver instead of the
VMware tools driver or the emulated e1000?
They are out of tree and subject to rotting. I had to use the patches
at [1] to even get them to compile on 9.1 and -current. I don't think
VMware puts much engineering resources behind it; there was a compiler
warning of a silly bug like:
if (foo) ;
do_something();
vmxnet3 has modern features LRO, IPv6 checksum offloading, etc that
the emulated e1000 lacks. In my test setup, e1000 tops out at 30MB/sec
but vmxnet3 goes to 50MB/sec. I'd like to hear other's experiences.
it'd be nice if we could get vmware to just support the drivers in tree..
by which I mean, just submit patches.. why do they need to have it out
of tree?
