What changes did you made to get the performance?
I've tweak some settings and im getting acceptable performance now but audio still breaks sometimes.
Setting I've applied:
Max PCoIP Session BW 7000 kb/s
PCoIP Audio BW Limit 500 kb/s
Turn Off Build to lossless
some settings on this guidehttp://www.vmware.com/files/pdf/techpaper/VMW-Tuning-Latency-Sensitive-Workloads.pdf
BIOS to High Performance and ethernetX.coalescingScheme disabled
