Because of replication between inhouse database servers and the 'Data Warehouse' the Virtual Machine and Web App were all in a Azure Virtual Network.

The problem was there can be network problems if a Web App inside a Virtual network wants to talk to Azure SQL Databases (which cannot be within a Virtual Network).

My solution was to

• configure an Endpoint on the Data Warehouse Virtual Server,
• take the Web App out of the Virtual network and make it point to the Virtual Server by means of the Endpoint

At this point all the delays went away and I could take off the MinPool Size settings (and Timeout which I later discovered did nothing anyway).
