- rdatarender_bench This is a benchmark for RDATA rendering performance comparing the basic Rdata objects and RdataField objects. It takes a command line argument that specifies an input data file. Each line of the data file should specify a single RDATA with its RR class and type, e.g. IN A 192.0.2.1 IN NS ns.example.com. Lines beginning with '#' and empty lines will be ignored. Sample input files can be found in benchmarkdata/rdatarender_*.
