Verbessern Sie die SQL Server-Abfrageleistung für große Tabellen

Ich habe eine relativ große Tabelle (derzeit 2 Millionen Datensätze) und möchte wissen, ob es möglich ist, die Leistung für Ad-hoc-Abfragen zu verbessern. Das WortAd hoc hier der Schlüssel zu sein. Das Hinzufügen von Indizes ist keine Option (es gibt bereits Indizes für die Spalten, die am häufigsten abgefragt werden).

Ausführen einer einfachen Abfrage, um die 100 zuletzt aktualisierten Datensätze zurückzugeben:

<code>select top 100 * from ER101_ACCT_ORDER_DTL order by er101_upd_date_iso desc
</code>

Dauert mehrere Minuten. Siehe Ausführungsplan unten:

Zusätzliches Detail aus dem Tabellenscan:

<code>SQL Server Execution Times:
  CPU time = 3945 ms,  elapsed time = 148524 ms.
</code>

Der Server ist ziemlich leistungsfähig (aus Speicher 48 GB RAM, 24-Kern-Prozessor), auf dem SQL Server 2008 R2 x64 ausgeführt wird.

Aktualisieren

Ich habe diesen Code gefunden, um eine Tabelle mit 1.000.000 Datensätzen zu erstellen. Ich dachte ich könnte dann rennenSELECT TOP 100 * FROM testEnvironment ORDER BY mailAddress DESC auf ein paar verschiedenen Servern, um herauszufinden, ob meine Datenträgerzugriffsgeschwindigkeiten auf dem Server schlecht waren.

<code>WITH t1(N) AS (SELECT 1 UNION ALL SELECT 1),
t2(N) AS (SELECT 1 FROM t1 x, t1 y),
t3(N) AS (SELECT 1 FROM t2 x, t2 y),
Tally(N) AS (SELECT TOP 98 ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM t3 x, t3 y),
Tally2(N) AS (SELECT TOP 5 ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM t3 x, t3 y),
Combinations(N) AS (SELECT DISTINCT LTRIM(RTRIM(RTRIM(SUBSTRING(poss,a.N,2)) + SUBSTRING(vowels,b.N,1)))
                    FROM Tally a
                    CROSS JOIN Tally2 b
                    CROSS APPLY (SELECT 'B C D F G H J K L M N P R S T V W Z SCSKKNSNSPSTBLCLFLGLPLSLBRCRDRFRGRPRTRVRSHSMGHCHPHRHWHBWCWSWTW') d(poss)
                    CROSS APPLY (SELECT 'AEIOU') e(vowels))
SELECT IDENTITY(INT,1,1) AS ID, a.N + b.N AS N
INTO #testNames
FROM Combinations a 
CROSS JOIN Combinations b;

SELECT IDENTITY(INT,1,1) AS ID, firstName, secondName
INTO #testNames2
FROM (SELECT firstName, secondName
      FROM (SELECT TOP 1000 --1000 * 1000 = 1,000,000 rows
            N AS firstName
            FROM #testNames
            ORDER BY NEWID()) a
      CROSS JOIN (SELECT TOP 1000 --1000 * 1000 = 1,000,000 rows
                  N AS secondName
                  FROM #testNames
                  ORDER BY NEWID()) b) innerQ;

SELECT firstName, secondName,
firstName + '.' + secondName + '@fake.com' AS eMail,
CAST((ABS(CHECKSUM(NEWID())) % 250) + 1 AS VARCHAR(3)) + ' ' AS mailAddress,
(ABS(CHECKSUM(NEWID())) % 152100) + 1 AS jID,
IDENTITY(INT,1,1) AS ID
INTO #testNames3
FROM #testNames2

SELECT IDENTITY(INT,1,1) AS ID, firstName, secondName, eMail, 
mailAddress + b.N + b.N AS mailAddress
INTO testEnvironment
FROM #testNames3 a
INNER JOIN #testNames b ON a.jID = b.ID;

--CLEAN UP USELESS TABLES
DROP TABLE #testNames;
DROP TABLE #testNames2;
DROP TABLE #testNames3;
</code>

Auf den drei Testservern lief die Abfrage jedoch fast augenblicklich. Kann mir jemand das erklären?

Update 2

Vielen Dank für die Kommentare. Bitte halten Sie sie auf dem Laufenden. Sie haben mich veranlasst, den Primärschlüsselindex von nicht geclustert auf geclustert zu ändern. Dies führt zu interessanten (und unerwarteten?) Ergebnissen.

Nicht gruppiert:

<code>SQL Server Execution Times:
  CPU time = 3634 ms,  elapsed time = 154179 ms.
</code>

Gruppiert:

<code>SQL Server Execution Times:
  CPU time = 2650 ms,  elapsed time = 52177 ms.
</code>

Wie ist das möglich? Wie kann ein Clustered-Index-Scan ohne einen Index in der Spalte er101_upd_date_iso verwendet werden?

Update 3

Wie gewünscht - dies ist das Skript zum Erstellen einer Tabelle:
