написано по мотивам Page Generation Time
немного кода (javascript с небольшими косметическими изменениями) взяты с форума ДК
оригинальный мод Page Generation Time, имхо содержит большую ошибку в определении времени генерации страницы - а именно при включенном гзип-сжатии неучитывается время самого гзипования, а оно не нулевое!!!
хотя это больше похоже модификацию модификации и требует наличия оригинального мода
(75% - это экономия траффика)
