Sounds awfully slow, given the startup time of the average JVM, plus the
time it takes hotspot to heat up.

There's also JPype, GCJ or JCC if running Java is an option, see e.g.

Should I say it? Serialisation and parsing are *fast* in lxml - don't know
about Saxon in Java, though. But given that both XSLT input and output can
be streamed, the I/O performance might not be that much of a problem
either (assuming large documents). Benchmarks will tell.

You could also write an HTTP based transformation service in Jython that
calls Saxon, and just run it in a permanently running JVM.
