The VMware Horizon View PCoIP server logs show "IPC Can't encode. Waiting. queue" after a random disconnect.
Problem The VMware Horizon View Client or PCoIP Zero Client experience a random disconnect from the VMware Horizon View session. Inspection of the PCoIP server logs show a high slice rate count after a random disconnect. The following example shows 192 …
Can a WAN accelerator be used to improve the performance of PCoIP sessions?
PCoIP does not benefit from a WAN accelerator, legacy WAN accelerator solutions use different methods to improve the performance of applications operating over congested networks. These methods include compressing packets, implementing proxy servers that …
Why is Adobe Flash choppy with VMware Horizon View and PCoIP Zero Clients?
Answer: Note: This article only applies to VMware Horizon View desktops that do not have physical GPU acceleration. To optimize the performance of Flash, ensure that the Flash player has hardware acceleration turned off: Right click on the Flash window …
Should I configure "Maximum Initial Image Quality" to 100 if I want lossless still image?
No. Regardless of PCoIP image-quality settings, still images are always lossless. The time it takes to display them depends on your image-quality settings and available network bandwidth. For most situations, it is recommended to use 40 for Minimum Image …
What does "IPC: Frame encode took xxx ms so far. Dropping down the quality to index x." in the log files indicate?
Answer: In this case, the imaging encoder has determined that too many bits were being sent in the upper portion of the frame (i.e. flooding) which causes the frame to take longer to encode, and therefore appears unresponsive to the user (> 750 ms to …
Will out of order packets impact a PCoIP session?
PCoIP will work when packets are becoming out of order between the two PCoIP endpoints. Re-ordering packets on PCoIP endpoints requires that packets are held in a queue/buffer while waiting to receive the packets that need to be put back into order.  With …
Why do I get poor performance on an MPLS network?
There are a number of configuration requirements for using PCoIP protocol on an MPLS network.  Prioritize PCoIP packets as a best practice Avoid packet loss Avoid out-of-order packets PCoIP protocol may consider out-of-order packets as lost if the data …
How do I ensure a fair allocation of bandwidth between multiple PCoIP sessions?
The PCoIP congestion avoidance algorithms are designed to ensure a fair allocation of bandwidth between multiple PCoIP sessions on the same network. There may be some networks where this doesn't work as well. There is also an associated time constant for …
How does PCoIP share bandwidth over the network?
The BW Limit is dynamically calculated and represents the bandwidth the PCoIP session estimates to be available given the network conditions. The calculation takes into account the existing bandwidth usage, packet loss and any high latency spikes. The …
