SQL Тот же самый запрос выполняется быстро в первый раз и медленно во второй раз.А потом чередует

У меня есть запрос.Когда я запускаю его в первый раз, он мгновенно возвращается.Примерно через секунду.Затем, когда я нажал F5, чтобы снова запустить ту же самую вещь без изменений, теперь она работает медленно, занимая более 30 секунд.Затем, если я снова нажму F5, он снова запускается мгновенно.И так далее, и он продолжает чередоваться.

Вот запрос:

Я предполагаю, что это связано с тем, что компилятор пытается оптимизировать мой запрос.Как мне сделать так, чтобы он оптимизировал для "@LocalDetailLevel = 'color'", так как это будет использоваться в 90% случаев?

Если кто-то может сказать мне, как добавить 

OPTION (OPTIMIZE FOR (@LocalDetailLevel = 'color'))

в мою хранимую процедуру, я думаю, что это решит многие мои проблемы.Моя хранимая процедура: 

GO
/****** Object:  StoredProcedure [dbo].[Z_N_FinalEcomDashAllItems]    Script Date: 9/24/2019 12:20:31 PM ******/
SET ANSI_NULLS ON

SET QUOTED_IDENTIFIER ON

@CompanyCode    VARCHAR(5),
@DivisionCode   VARCHAR(5),
@FromDate       DATETIME,
@ToDate         DATETIME,
@DetailLevel    VARCHAR(50),
@OrderBy    VARCHAR(50)


AS

DECLARE @LocalCompanyCode VARCHAR(5)
SET @LocalCompanyCode = @CompanyCode

DECLARE @LocalDivisionCode VARCHAR(5)
SET @LocalDivisionCode = @DivisionCode

DECLARE @LocalFromDate DATETIME
SET @LocalFromDate = @FromDate

DECLARE @LocalToDate DATETIME
SET @LocalToDate = @ToDate

DECLARE @LocalDetailLevel VARCHAR(50)
SET @LocalDetailLevel = @DetailLevel

DECLARE @LocalOrderBy VARCHAR(50)
SET @LocalOrderBy = @OrderBy

BEGIN
... The query from above
END

Я пытался добавить ее следующим образом 

BEGIN
... The query from above
OPTION (OPTIMIZE FOR (@LocalDetailLevel = 'color'))
END

Но там написано "Неверный синтаксис рядом с ключевым словом" OPTION ". *

ЕслиЯ избавляюсь от всех BEGIN / END после предложения IF и имею только один начальный конец для всей процедуры, я получаю «Переменная« @LocalDetailLevel »указана в предложении OPTIMIZE FOR, но не используется в запросе.«

...
