What can i do to make it faster on the > slow machine? Well, multiple CPU's are probably not the reason, if the machines are not loaded otherwise. (I am assuming you are talking about running one transform at a time, not multiple sessions concurrently). It is likely there is some other difference, may be your compiler, java vm (if you're using java), OS, etc. Which XSLT engine are you using? In my book, of course, both 10 minutes and 42 seconds are quite unacceptable, and you shouldn't have to spend time trying to optimize it by hand. That's what optimizing compilers are for. <plug>If you'd like it to run much better than either 10 minutes or 42 seconds, check out DataPower's XML acceleration solutions, from DGXT (an optimized interpreter) to XSLJIT (a JIT compiler for XSLT) to the XA35 (a network device for XML & XSLT acceleration). http://www.datapower.com Our goal is to remove any worries about XML scalability -- you worry about the app, we worry about the speed. </plug> \\ Eugene Kuznetsov \\ eugene@xxxxxxxxxxxxx \\ DataPower Technology, Inc.
