RoR on Windows Server 2003.. Is there any problem?

Hello,

I'm currently wirking in my first commercial project with RoR. The client is asking me if we can use Windows Server 2003 or Windows 2000, because he has 3 application running on 3 virtual private servers running Windows, and he thinks that the most efficient way to go for this new application in RoR would be to create a new virtual private server in that big computer.

I'm currently developing applications with RoR in Win XP, using the last version of InstantRails, and everything seems to work fine, so I told him that I was going to investigate, and give him an advice.

Now, I did just that, and I found in this group some posts discusing this issue. The conclusion is that you can run RoR on Windows, but everyone still prefer to run it on Linux. Then, my question is... why? Is it really better to run RoR in Linux/Apache/Mongrel than Windows/Apache/Mongrel (for example)?

Any comments would be appreciated.

Thanks! Federico F.
