The best our Weblogic admins were able to do is send me the thread dump in my original mail. I have some built in performance profiling functionality in the app in question and it helped me isolate the Transformer.transform() call. I downloaded an eval of JProbe and the lowest level of granularity I could get from it was the Transformer.transform() call which didn't really help. I assume there must be some way to sniff out what was going on inside that transform call but my trial license expired before I had a chance to figure it out. -----Original Message----- From: Joseph Kesselman [mailto:keshlam@us.ibm.com] Sent: Friday, May 21, 2004 12:40 PM To: 'xalan-j-users@xml.apache.org' Subject: Re: intermittent XALAN performance issue Hm. The closest I've seen to that set of symptoms was when I had set the JVM's maximum heap size much too large, with the result that the beast was swapping itself to death rather than running GC and bringing itself back down to a reasonable working set... or when we were reading a file from the network and there were bandwidth problems on the wire. I don't suppose you could run this under a performance analyser and determine where the time is going...? ______________________________________ Joe Kesselman, IBM Next-Generation Web Technologies: XML, XSL and more.
