+# A. Импорт данных
+Обработка medium файла занимает ~ 1мин40сек, по памяти - 111MB
+
+Сразу же приступил к переписанию на потоковую обработку, выделил код в класс в app/services/reload_json.rb, добавил frozen string literal, все инсерты в таблицы заменил на импорты
+После оптимизации обработак medium файла - ~ 1 сек, память - 87 MB
+
+Обработка large.json - ~ 7.6 сек, память - 87MB
+
+Обработка 1M.json - ~ 68 сек, память - 116MB
+
+По отчетам профилировки по CPU и памяти не нашел точек для оптимизации
+# Б. Отображение расписаний
+Начну с rack-mini-profiler
+
+Без профилировщика страница с 1004 трипов загружается за 3.4 секунды, с профилировщиком - 19 сек
+
+Профилировщик показал 450 запросов в app/views/trips/index.html.erb, добавил ```includes``` моделей в app/controllers/trips_controller.rb, заменил @trips.count на @trips.size
+
+Теперь страница загружается за 11.4 сек, кол-во запросов сократилось до 6
+
+Судя по логам и профилировщику большинство времени уходит на рендер паршалов, об этом же говорит и rails panel
+![Alt text]()
+Перенес весь код касаемый одного трипа в паршал, избавился от рендера остальных паршалов, результат
+![Alt text]()
+Общее время запроса в среднем 315ms
+
+Считаю на этом можно остановиться, т.к. улучшение запросов почти не принесет пользы, а импорты могут замедлиться из-за добавления индексов
