I'm afraid I know nothing about AntennaHouse or what facilities it provides
for invoking different XSLT processors. However, a startup cost of 2.5s for
starting up a Java VM doesn't surprise me in the slightest. I'm slightly more
surprised by the 5s for .NET, since I was under the impression .NET startup
costs were lower than Java.

Are you sure they are invoking MSXML via a command line interface? I would
think it's more likely they are invoking it directly via an API call, in which
case it will be much faster than any processor invoked using via a command
line exec.
