>From the information provided it is not immediately apparent to me what your problem is. But from crude benchmarking I've done.. ESQL is SIGNIFICANTLY faster than the SQLTransformer.. To experience this, use apbench on the http://localhost:8080/cocoon/samples/poi/statetax.xls and statetax2.xls (filenames are approximate) examples that come with cocoon. The statetax2 example is more complicated and has groupings and stuff, but its STILL several times faster than the SQLTransformer version. I found my results to be consistent when used other ways as well.
