Benchmarking Remote CMD and Powershell Invocations with WinRM in Test Kitchen

Notes

• The executor in the code is a CommandExecutor which sets up and reuses a remote shell session across calls and recyles it before the maxiumum commands-per-shell limit is reached.
• The vanilla object is a regular WinRM::WinRMWebService instance which sets up and tears down a shell for every CMD and Powershell script invocation.
• The Powershell script variant is really running a powershell -encodedCommand <ENCODED_SCRIPT> over CMD.
• The file appending operation isn't very taxing on the Windows host but simulates a chunked file upload and so tries to measure the relative cost of command invocations vs. measuring the time for the commands to execute.

Observations

fnichol

If you're using ChefDK and find you can't wait for the next release to come out (which will out be shortly), you might want to give the chefdk-update-app project a spin to update test-kitchen (follow the setup instructions in the README).

Upgrade test-kitchen

Upgrade test-kitchen with the following for Unix-based workstations:

sudo -E ./bin/chefdk-update-app.sh test-kitchen -r v1.4.0

Setting Up Vagrant With Ubuntu 10.10 (32-bit)

Setup

First you need to ensure that VirtualBox is installed. Current vagrant release is not working with VirtualBox 4.x, so get a previous 3.2.x version (currently 3.2.10 which updates to 3.2.12) from http://www.virtualbox.org/wiki/Download_Old_Builds_3_2.

Next install the vagrant gem and download the Ubuntu 10.10 32-bit vagrant box I built up:

gem install vagrant

vagrant box add maverick32 http://dl.dropbox.com/u/2297268/maverick32.box
