Timeout

This article is based on my Citrix Synergy 2015 session and is the second in a mini-series on Group Policy performance. All measurements by uberAgent on Windows Server 2012 R2 with Citrix XenApp 7.6 in a steady state. Please start reading with the first article.

I have been using Windows 8 Client Hyper-V for a while now and must say it works like a treat - except for one thing: it is practically impossible to give VMs at the same time NATted internet access and connect them to other VMs and to the host. Windows Internet Connection Sharing (ICS) just does not work reliably and I have found no other product to use instead.

Today I was looking for the source of frequent delays when setting permissions from my new application SetACL Studio. I sprinkled the code with timestamped debug statements like these… System.Diagnostics.Debug.WriteLine(DateTime.Now + " - 1"); // Do something System.Diagnostics.Debug.WriteLine(DateTime.Now + " - 2"); …and found that the delays always had a duration of seven seconds. Wait - “inexplicable” delays of constant length - that smells of timeouts!
