xalan performance

I'm using Xalan 1.2, and I'm having quite severe performance problems in a
web based application that I have built.  My XML stream takes about 3
seconds to create, but then actually applying XSL to the XML to generate
HTML is taking a further 10-13 seconds.  I've tried precompiling the
stylesheets, but I only save about 1 second.

My stylesheets are nested hierachically (I have a master sheet which imports
subsheets, and they in turn can import subsheets themselves - this helps me
manage the complexity of the sheets.

I'm at wits end - is there anything that gives better performance than this
(Open source or pay cash)

(I'm on a high spec Solaris machine, with JDK1.2)

Any pointers appreciated - I've started doing page caching, but for a
dynamic app, this is not really ideal...)
