It’s just data

Benchmark update

In the previous benchmark I compared REXML to libxml2.  In order to get a deeper understanding of where the time was being spent in REXML, I also compared REXML Document.new against Marshal.load of the same data.  The result was that 2/3 of the time was spent in the parsing.

Now to explore the datastructure that REXML uses.  In order to do this, I convert all of the data into a series of nested arrays of strings.  Marshal the results, and then compare the times it takes to reconstruct the Nodes.

test7 REXML Element.new Ruby 1.8 12.877s
test7 REXML Marshal::load Ruby 1.8 1.736s
