Defect Number

Enhancement Number

Cause

This is not an OpenEdge Defect. The performance issues were determined by Consultants to be an issue with the default NIC configuration that the VM was configured to emulate.

Resolution

VMware ESXi6 defaults to NIC E1000. Switching to VMXNET3 resolved all the performance issues. For further information contact vendor support.

It is advisable to upgrade to Upgrade to VMware ESXi 6.5 or later where an issue with the VMware vmxnet3 network driver when a VM is configured to use multiple cores spread across multiple virtual sockets causes similar performance issues.
VMware vmxnet3 driver + multiple CPU sockets = poor performance
