The truism is that if you are worried about efficiency, you need to test using the processor that you are going to use in production and using something like the real data. This example from my tutorial about testing XSLT [1] shows the result of profiling the same stylesheet and data in both xsltproc and Saxon: the two XSLT processors agreed on which were the two most time-intensive templates, but after that, their results differed. And in this instance, using the Saxon timing switch and profiling stylesheet as shown in the tutorial (and in the Saxon documentation [2]) will help you identify your hotspots.
