i trying convert list of jsons list of pipe delimited strings. 1 of problem json tags can missed in lines , final list has include ""|""|"" empty strings in place of missed tags. there no guarantee every json have same tags in same sequence. number of pipe delimited strings has remain same. changed json module simplejson , use multiprocessing strongs cpu's(32). result still poor. use of pyinstaller doesn't improve anything. need community help.
i tested different json parsers: simplejson, ujson, json, yajl , nothing helped. came cjson , decreased time 28 minutes 1.5 minutes. have no idea "why?" works rocket despite other solutions implemented in "c".
