У меня есть объект, который я сериализую в Json, используя NewtonSoft Json.Net. Объект относительно велик, в результате Json составляет около 300 КБ, но процесс сериализации занимает около 60 секунд.
Объекты, которые будут сериализованы, - это просто POCO.
Используемый мной код
string json = Newtonsoft.Json.JsonConvert.SerializeObject(data, Formatting.Indented);
Есть ли что-то, что можно сделать для ускорения сериализации, добавления атрибутов и т.д.
EDIT: Я только что протестировал с помощью сериализатора сериализации ServiceStack.Text Json, и это занимает 48 секунд, все еще довольно медленно.
