Virtualized Web App performs poorly



Seriously if you're an admin, you know there is a lot more to performance than an underlying layer.

Virtualization is the magic wand = wrong
App will live happily ever after = do they now?
I have cron/scheduled tasks jobs running
What about those Virus scanners? Do they know you're benchmarking your VM?
Questions, Questions...

Well anyways this article got analysed by Slashdot users as media continues to thrash VMware's product by running outdated products, beta products and in many cases also beta benchmark tools!

Original article says:

The purpose of this article is to explore the performance impact of virtualization on a web application that uses typical development methodologies. The goal is to give administrators some idea of the performance impact that virtualization will have on their applications as they become loaded - and how it is different from the native servers. For our reference application, we will use the ASP.NET Issue Tracker System, part of the Microsoft ASP.NET Starter Kit. While this sample application is relatively simple, it makes use of one of the most common development frameworks and the code is typical of many larger IT web applications.

We ran 4 load tests on the application. The first measured the performance of the web application running on a native Windows 2003 Server installation. The second test measured the performance of the web application running on a virtual Windows 2003 Server installation running within VMware Server 1.0.1. VMware ran on Linux (CentOS 4.4). The base hardware for both machines is a Dell Poweredge SC1420 with dual Xeon 2.8GHz processors. The virtualized server has the same memory available to it (2G) as the native server (which implies that the physical machine running VMware has more memory). Since the Intel Xeon processor supports hyperthreading, there was some debate as to the impact of hyperthreading on the virtualized machine. So we decided to run two additional tests with hyperthreading disabled for both the native and virtualized servers.
