SQL оптимизация запросов с использованием динамического c запроса

Execution planExecution Plan У меня есть следующая хранимая процедура. Он использует общее табличное выражение и табличную функцию. Выполнение этого sp занимает 600 мс. Я использовал динамический запрос c, чтобы избежать использования табличной функции, а время выполнения сократилось примерно до 300 мс. Можно ли дополнительно настроить этот запрос выбора так, чтобы время выполнения уменьшалось до 100 мс.
