Очень, очень медленное выполнение Entity Framework Query

Я использую 6.1.1 структуры сущности для SQL Server 2012.

Я применил данный вопрос к этой проблеме.

При непосредственном запуске нашей БД (т.е. Из SQL Generated) этот запрос отвечает в <15 мс.

Однако при обработке в Entity Framework это ~ 650 мс до материализации к проекции (таким образом, не вызывает проблем с отслеживанием)

Кроме того, при использовании Web API и Odata для достижения 100-го уровня он еще медленнее. (т.е. если я сначала сделаю.ToArray() по результатам в конечной точке в контроллере веб-API, это быстрее, чем отфильтрованный верхний запрос 100 через odata.

Хуже того, запрос inlinecount по oData, который приводит к сбою групповой последовательности, которая генерируется Entity Framework, которая является нечетной, занимает <10 мс для обработки на сервере, но занимает столько же времени, что и Entity Framework для обработки, как полный выбор тем самым удваивая время обслуживания.

Я могу понять некоторые издержки, но мы говорим о 100 записях в проекции, для обработки этого не должно занимать больше половины секунды.

Кроме того, я ожидал, что, учитывая сложность предложения where (сгенерированного с использованием предикатов), во второй раз это было поражено, что он будет значительно быстрее из-за динамического кэширования в EF 5+, но он не делает никаких разница вообще.

Я могу предоставить вам DTO, в котором он проектируется, если это имеет значение, но это просто строки и datetimeoffsets прямо без каких-либо вычислений или чего-то еще.

Также обратите внимание, что все тесты выполнялись в режиме деблокирования, а не в режиме отладки. И таймеры были использованы, чтобы изолировать 2 отдельных запроса в пользовательском форматировании и времени, сколько времени потребовалось для поддержки структуры сущностей.

Я подошел к уровню БД и создал считыватель БД и зациклился на результатах и вручную создал DTO для работы (все из них, а не отфильтрованные), используя тот же самый сгенерированный запрос, просто добавляя разные значения для параметров и он завершился в течение <30 мс для справки.

Если вы хотите, чтобы я каким-то образом предоставил вам встроенный предикат, который сгенерировал это, сообщите мне и дайте мне инструкции, и я буду рад сделать это.

Здесь результирующий запрос (который снова запускается через 30 мс, но Entity Framework занимает 2,5 секунды, чтобы получить результат и вывести его с помощью WebAPI:
