saxon for windows
The XSL-as-web-service is intriguing but I do have some concerns about a command-line processor. The comment George makes about the JVM startup overhead can be extended to most things run from the command line - there will be system-related activity that has little to do with the work that will be incurred each time. If this is a concern for XSLT the processor can be properly hosted within the web server. Saxon is ideal for this as it is Java based. It would be fairly straightforward to create a web service for this purpose that could be dropped into a J2EE container and run on whatever kind of platform you like (Windows, Linux, Unix, Mac, etc.), and it doesn't have to be the same OS as the client. With Saxon's support for pipelining transformations some of those concerns could be addressed as well. My main concern with the web service approach in general is the amount of data that would need to be transmitted across the network. That may be the real limiting factor in this.

What about the java start up time? You will add that at each run.
And if you run the transformation only once then I think you will not get the best of Java either - I always hear that if you want to measure how much time a stylesheet takes for processing you should not look at the times of the first runs.

My 2 cents...
