The problem with PCOIP performance is solve. The test VM has only one vCPU. We did't realize our error before... With two vCPU, with stressful movie trailer (1080p) the results are great. Better than View 5.2.
Now the strange bug with laggy flash video under VADC is not solve. I have posted below what happened. Does someone got the same results? It's easy to test.
