That was VMware/Linux but I have also seen some pretty horrific performance on badly-tuned Hyper-V, on good hardware. I'd encourage you also to try to reproduce the performance issue(s) outside of OpenEdge and the associated application, e.g. with utilities or synthetic benchmarks to do disk reads and writes (sequential/random, read/write), network transfers, etc. As Carey said, try to compare with a comparable reference system that has decent performance. More than once I've seen admins refuse to help with a performance issue because "Progress is just slow", so the issue can't be theirs. Reproducing outside of OpenEdge helps to stop that excuse before it starts.
