I don't think it wouldn't be a bold statement for me to say that "out of the box" Teradici's PCoIP display protocol can perform flawlessly on a LAN or High-Speed WAN environment. However this may not always be the case and certainly over slow remote WAN links PCoIP can present a poor user experience. (Equally, so can any other remote display protocols)

Due to the nature of VDI, remote offices with low bandwidth, high latency connection are all to familiar. Initially performance is often poor and occasionally unusable. It's at this point you can throw in the towel and declare that VDI is not for your business OR you can try to workout what is causing the poor performance and try to improve it.

So where do you start?
