It was a very nice surprise for me to find myself among XSLT celebs in this year's Programmers' Choice Nominations: see below (and VOTE :-) http://www.activestate.com/Corporate/ActiveAwards/ --Jacek PS. I am also delighted to see that XSLTC, as part of Xalan, now ships in volume with IBM's Java

Kelly, have you tried XSLTC? Should be a very simple matter to run the test and I'd be curious about your performance results. As Joe says, not much can be learned when you do not quote an XML/XSL example. --Jacek --- Kelly Zeng <[EMAIL PROTECTED]> wrote: > Hi, > It looks to me that Saxon is

XSLTC and Sun's j2sdk1.4.0_01 problem

2002-07-02 Thread Jacek Ambroziak
Guys, as I've been benchmarking various XSLT solutions for Java I noticed that XSLTC takes forever (practically loops) to complete the popular XSLTMark benchmark suite. It runs OK on 1.4.0. I am running Red Hat Linux 7.1, kernel 2.4.18. XSLTC comes either from Sun's XML Pack Summer 02 or Xalan 2

Thank you Tom very much. And indeed I will need your help to ensure that changes to the codebase don't break anything. The code has become complicated, at places -- I will argue -- unnecessarily so, so extra care has to be taken. Let's communicate next week on your best practices in esuring qual

XSLT benchmarks: dbonerow

2002-02-20 Thread Jacek Ambroziak
Setting the stage: Today's XSLTC translets perform abysmally on the 'dbonerow' benchmark. The XML document is a set of 10^4 records and the stylesheet contains one template designed to match (and process) one of the records; XSLT essentially performs a search by matching. On my machine 10 iterat

You guys may find another data point interesting... (I am using Sun's newest 1.4 on Linux) I reran the test with '-verbosegc' flag gathering GC info into files. and then counted Full garbage collections grep Full gcXSLTC | wc -l grep Full gcXT| wc -l and so on. The results: XSLTC21 X

Stefano, that is cool! Except for the mysterious 'dbonerow'. I will attempt to fix it an in general I am going continue to follow my original vision to make XSLTC a good technology for people to actually use. You are right, there are multiple 'goto's' in the generated bytecodes (although the by
