Yorick Peterse 8db77c0a09 Count newlines of text nodes in native code. ... Instead of relying on String#count for counting newlines in text nodes, Oga now does this in C/Java. String#count isn't exactly the fastest way of counting characters. Performance was measured using benchmark/xml/lexer/string_average_bench.rb. Before this patch the results were as following: MRI: 0.529s Rbx: 4.965s JRuby: 0.622s After this patch: MRI: 0.424s Rbx: 1.942s JRuby: 0.665s => numbers vary a bit, seem roughly the same as before The commands used for benchmarking: $ rake clean # to make sure that C exts aren't shared between MRI/Rbx $ rake generate $ rake fixtures $ ruby benchmark/xml/lexer/string_average_bench.rb The big difference for Rbx is probably due to the implementation of String#count not being super fast. Some changes were made (https://github.com/rubinius/rubinius/pull/3133) to the method, but this hasn't been released yet. JRuby seems to perform in a similar way, so either it was already optimizing things for me or I suck at writing well performing Java code. This fixes #51.		2014-09-25 22:49:11 +02:00
