В продолжение поста #1637419 проверил производительность ujson относительно Python 2.7.2 на рабочем компе и VPS'ке у Linode. Ну и Python 2.6.7 для создания контраста. Собрать под PyPy не вышло, хотя поддержка заявлена(readme читал). С удивлением обнаружил, что собирается под 3.x, однако падает при импорте — пичалько, но пофиксить знаний не хватает.
Результаты в камментах.
А резюме примерно такое: стандартный json модуль в Python 2.7 прекрасен и его достаточно в 95% случаев, но в специфических задачах ujson может только улучшить картину.
