http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6849 Xerces2 performance difference with DOM compared to Xerces1???? Summary: Xerces2 performance difference with DOM compared to Xerces1???? Product: Xerces2-J Version: 2.0.0 Platform: Other URL: http://xml.apache.org/xerces2-j/index.html OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: DOM AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Hi, I am writing a technical note evaluating the performance of different parsing implementations. These included Xerces1.4.4 and Xerces2.0.0. However I found Xerces2 performance decreases when using the DOM specification. I based my results on one level deep XML files. This data was read into a string buffer and subsequently parsed. Each file (there were 12 of varying size) was parsed 100 times and averages were obtained from these results. The heap size of the machine was set at 256MB. The results when using SAX show negligible performance differences between Xerces1 and Xerces1. Have you any idea why I may be getting a 20% performance difference when using DOM? What perhaps am I doing wrong? Should Xerces2 perform worse that Xerces1 when parsing DOM? Thanking you in advance, Anne Meade --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
