Michael Osipov commented on JXPATH-183: --------------------------------------- That is a terrible piece of code which creates 16000 new integer objects. [{{Integer#valueOf}}|http://docs.oracle.com/javase/7/docs/api/java/lang/Integer.html#valueOf%28int%29]. should give a better performance here. > XMLGregorianCalendar existence adding a lot of performance penalty > ------------------------------------------------------------------ > > Key: JXPATH-183 > URL: https://issues.apache.org/jira/browse/JXPATH-183 > Project: Commons JXPath > Issue Type: Improvement > Affects Versions: 1.3 > Environment: Windows 7, Amazon Unix, Weblogic > Reporter: Ganna Shmatova > Labels: performance > > We're using JXPath to parse some input from a client. When they give us a > valid date it gets transformed from a SOAP message into Java objects. When > this happens JXPath queries suddenly take 1-8 seconds more (depending on > system -- the optimized system it's 1 second, dev & test machines it's 8). > Kicker is, we don't even look for this field. Just its existence does it. > (we've quickfixed to omit the xml tags before the string is parsed into Java > for now) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
