h1. JsonBenchmarkCpp
JsonBenchmarkCpp is a small program to benchmark various JSON frameworks in c++
Currently supports following libs,

or use your favourite build system to compile and link main.cpp with the libs.
h2. Results Summary
Frameworks ranked in the order "libjson":http://sourceforge.net/projects/libjson, "json_spirit":http://www.codeproject.com/KB/recipes/JSON_Spirit.aspx and "Cajun":http://sourceforge.net/projects/cajun-jsonapi for both parsing and writing speeds
Eg:
bc. $./JsonBenchmarkCpp > results.dat averydb@debian:~/gits/JsonBenchmarkCpp$ cat results.dat
cajun 669 160
json_spirit 14907 731
libjson 139 203
Avery 35 55
json_parser 114
Here the numbers shows time taken by each lib for the particular operation in microseconds. libjson is a clear winner among the three. Sample results and corresponding graphs are available in results directory. For accurate results, replace the content of file data.json with your JSON data and run the executable.
Use the gnuplot script results/graph.p to draw bar diagram out of this data:
bc. $ ./graph.p > graph.png
h3. Thanks
Thanks to the library authors for their effort and time. You saved me from reinventing the same wheel again!
Special thanks to Jonathan Wallace, for actively developing libjson and helping me with my queries.
