Hi, Wonder, if any one has done performance testing on xquery processors that have java API and has some data to share with. I have recently picked saxon for xquery because of its reputation with XSLT and also being used for conformance testing in the xquery standardisation process. I am not sure if there is a good competitor that i could evaluate and compare. If there is one, please do recommend it to me. What i have done on my side are a couple of simple tests on saxon document loading and xpath expression evaluation in saxon versus the Xpath that is built into Java5(I believe it is the same as what used to JAXP xpath in java 4). Here is what i found. Saxon documents take a longer to build and load and consume a more of the java heap size, but their xpath expression evaluations are much faster. Also the memory it consumes for the evaluation seems to be less compared to Java5 xpath. For the same document and same xpath expressions that lead to a large number of results, the java5 xpath expression evaluation was eating up all the heap while saxon xquery processor yielded the results. Since java5 does not support xquery, i could not evaluate FLWOR expressions and other xquery specific stuff. I would like any other insights into saxon's xpath/xquery peroformance either by itself or in comparison with other xquery processors. Thanks a lot Manava __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
