Why is D/Tango so fast at parsing XML?
http://dotnot.org/blog/archives/2008/03/12/why-is-dtango-so-fast-at-parsing-xml/I have been getting questions concerning the performance of Tango in the XML benchmarks I have been running, with people wondering how something that is not C/C++ could be so fast. “They must be cheating!” This post intends to explain how D, and subsequently Tango, can perform so well, even against C/C++. …

XML Benchmarks - Parse/Query/Mutate/Serialize
http://dotnot.org/blog/archives/2008/03/10/xml-benchmarks-parsequerymutateserialize/I created a benchmark similar to the one that VTD-XML uses. Basically, since most xml processing is mutation, this benchmark parses an input xml file, executes various xpaths on the file, modifying the document in 2 instances, and then serializes the new document. …

XML Benchmarks - Parse/Query/Mutate/Serialize
http://dotnot.org/blog/archives/2008/03/10/xml-benchmarks-pa...have xpath or xpath-like support, if you know of another one, please submit me some code, and I will be happy to run and aggregate the results): DOM4J - TransformDOM4J.java Java6 DOM - TransformDOM.java VTD-XML - TransformVTD.java Tango Document - transformtango.d After the run, I take the average cycle time, and turn that into the followin graph showing cycles per second. blog.xml is 1.3MB, so you can multiply these numbers by 1.3 to get the Megabytes per second number for each tool.

XML Benchmarks - RapidXml
http://dotnot.org/blog/archives/2008/03/09/xml-benchmarks-ra...test. RapidXml is written in highly-tuned C++, and does give Tango a run for the money. I am really glad we are starting to add some non-Java alternatives, so we can see what native code can do. Without further ado, the code is bench_rapidxml.cpp, which was compiled via: g++ bench_rapidxml.cpp -O2 -o bencn Results for hamlet.xml: stonecobra@jeff-home:~/xmlbench$ vi bench_rapidxml.cpp stonecobra@jeff-home:~/xmlbench$ g++ bench_rapidxml.cpp -O2 -o bench stonecobra@jeff-home:~/xmlbench$ ./bench

XML Benchmarks - Updated graphs
