提高SQL Server中插入的速度

我試圖在SQL Server 2008中優化以下查詢。執行計劃顯示此查詢相對於批處理爲90％。插入顯示75％。我正在尋找一個選項來進行批量插入，併發插入等。有人可以拋開光速加快這一進程。我可以做SqlBulkCopy或使用OpenRowset功能嗎？我已確保有所有在那裏的條件提高SQL Server中插入的速度

INSERT INTO [xxxxxxx].[dbo].[xxxxxxx] WITH (Tablock) 
    SELECT 
     s.companyId, 
     ti.tickerSymbol, 
     s.securityName, 
     ex.exchangeName, 
     cur.currencyName, 
     primaryFlag = CASE 
         WHEN ti.primaryFlag = 1 AND s.primaryFlag = 1 
          THEN 1 
         ELSE 0 
         END, 
     ti.tradingItemId, 
     peq.pricingDate, peq.priceOpen, 
     peq.priceHigh, peq.priceLow, peq.priceMid, 
     peq.priceClose, peq.priceBid, peq.priceAsk, 
     peq.volume, peq.adjustmentFactor, peq.VWAP, 
     mc.marketCap, mc.TEV, mc.sharesOutstanding 
    FROM 
     ciqsecurity s 
    INNER JOIN 
     CoreReferenceStaging.dbo.MarketDataTemp1 a ON a.companyId = s.companyId 
    INNER JOIN 
     ciqtradingitem ti ON s.securityid = ti.securityid 
    LEFT JOIN 
     ciqpriceequity peq ON peq.tradingitemid = ti.tradingitemid 
    LEFT JOIN 
     CoreReferenceStaging.dbo.MarketDataTemp2 mc ON (mc.companyId= s.companyId AND mc.pricingDate = peq.pricingDate) 
    INNER JOIN 
     ciqExchange ex ON ex.exchangeId = ti. exchangeId 
    INNER JOIN 
     ciqCurrency cur ON cur.currencyid = ti.currencyId 
    ORDER BY 
     peq.pricingDate DESC

我試圖切片INSERT INTO批次字段的索引，但它似乎需要更長的時間。對於e.g以下

DECLARE @BatchSize int = 1000 

WHILE 1 = 1 
BEGIN 

INSERT INTO [xxxxxx].[dbo].[xxxxxxx] with (Tablock) 
select 
    s.companyId, 
    ti.tickerSymbol, 
    s.securityName, 
    ex.exchangeName, 
    cur.currencyName, 
    primaryFlag = case when ti.primaryFlag = 1 and s.primaryFlag = 1 then 1 else 0 end, 
    ti.tradingItemId, 
    peq.pricingDate, 
    peq.priceOpen, 
    peq.priceHigh, 
    peq.priceLow, 
    peq.priceMid, 
    peq.priceClose, 
    peq.priceBid, 
    peq.priceAsk, 
    peq.volume, 
    peq.adjustmentFactor, 
    peq.VWAP, 
    mc.marketCap, 
    mc.TEV, 
    mc.sharesOutstanding 
from ciqsecurity s 
    inner join CoreReferenceStaging.dbo.MarketDataTemp1 a on a.companyId = s.companyId 
    inner join ciqtradingitem ti on s.securityid = ti.securityid 
    left join ciqpriceequity peq on peq.tradingitemid = ti.tradingitemid 
    left join CoreReferenceStaging.dbo.MarketDataTemp2 mc on (mc.companyId= s.companyId and mc.pricingDate = peq.pricingDate) 
    inner join ciqExchange ex on ex.exchangeId = ti. exchangeId 
    inner join ciqCurrency cur on cur.currencyid = ti.currencyId 
order by peq.pricingDate desc 

IF @@ROWCOUNT < @BatchSize BREAK END

結果與組統計上
