To follow-up on this, we may be seeing some different issues. What we are seeing at our customer (a major US bank) is that it takes about 5 MINUTES for each WFA command block to start execution. The server being used is pretty much cut off from the outside world, so I thought it may have had something to do with checking for certificate revocation. But we tried disabling that by various methods, including as shown in this article: http://velemental.com/2012/01/01/optimizing-the-execution-of-powershell-and-powercli/
Nothing made a difference. If we open a powershell window on the server, it seems to open in a normal amount of time. If we load the ONTAP module, it loads normally and quickly. So we don't see the issue by using the powershell command window.
Our onsite guy at the customer is going to look into getting the server more outside access or adding it to the domain (which is currently isn't on).
