Hi,
Is it possible to use XSLTC [1] in XML Filter to speed up the transformations?
It is a matter of XSLTC reliabilty, if the result has a similar quality
as with the Xalan processor (from the same xalan.jar). I had once
problem with the XHTML export perhaps it has changed, havn't checked for
while and I must admit forgot about my bug-id.
But instead of switching to XSLTC, I would personally rather switch to
Saxon-B 9.0 [2] providing XSLT 2.0, XPath 2.0 and XQuery 1.0.

I have a large and somewhat complex filter and it runs much faster the
second time I use it after starting OOo than the first. I imagine OOo is
either caching something or compiling it.
Yes, there is a caching. The stylesheets are being parsed only once and
than cached after first usage.
But even Java start up might have its part.
Not sure if OpenJDK 6.0 build b10 [3] has the same performance
improvements as the Java SE 6 update 10 [4], but it will improve a lot
in the future.
Cheers,
Svante
