Here, we tested four of the most common applications used in virtualized desktop environments: Microsoft Office 2007 including Word, Excel, PowerPoint and Outlook. Similar to the OS launch tests, an Adam launch is one where Windows has been completely rebooted, and then given a few minutes to finish its startup process. A successive launch test is done repeatedly without restarting Windows.
Most applications, including these, launch very quickly with the worst performance being under Windows 7 for Adam launches. Even so, launches are so fast on both virtualization products that we focused exclusively on the Adam and not the successive launches.
Here are the results:

In many cases, applications today perform so well and so fast, even under virtualized environments, that anyone would be pleased for small documents and activities. We focused our efforts on larger tasks that were not only large enough to measure, but will also stress the systems to some extent.
For Microsoft Word, we took a very large document and did a global search and replace of about 95,000 items. For Microsoft Excel, we ran a macro that generated a large quantity of random numbers, and filled cells with them. And, for Outlook, we had the application do an IMAP sync with a mail server on the test LAN).

The tests performed used the same web page ... with and without SSL.
