Virtualizing Cuts Web App Performance 43%

czei writes "This just-released research report, Load Testing a Virtual Web Application, looks at the effects of virtualization on a typical ASP Web application, using VMWare on Linux to host a Windows OS and IIS web server. While virtualizing the server made it easier to manage, the number of users the virtualized Web app could handle dropped by 43%. The article also shows interesting graphs of how hyper-threading affected the performance of IIS." The report urges readers to take this research as a data point. No optimization was done on host or guest OS parameters.

I do like the idea of a variably sized beowulf cluster running a floating number of package (LAMP) servers. Get more clients? Add more VLAMPs. Things slowing down? Add more hardware.

I started getting aroused as I read your post. This is highly disturbing.

But then again, I've got 6 Gigabit NICS load balanced on a Gigabit backplane with the VMs all running on an independent SAS array on a quad processor hyperthreaded box with 32 GB of RAM. But perhaps your box has equally as good specs, I don't know.

Oh yeah? Well my Johnson is longer than yours, and my son can beat up your son.
