I just noticed that our virtual switch is set to 100 Half Duplex.
Should I change this to Auto? We're having performance issues.
The Adapter is a Broadcom NetXtreme II BCM5709
The change will help only if your uplink physical NIC is running at 1Gbps full duplex. Check esxcfg-vswitch -l and then see with esxcfg-nics -l what is the actual speed of your adaptor.
P.S : If you think that the answer is helpful please consider rewarding points.
Sometime the UTP cable or patch panel connectivity may caused the problem as well.
