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. [1] - http://ogris.de/vmware/ > -- > Joel >Received on Mon Aug 05 2013 - 20:52:12 UTC
