  • RE: Improving Delete Performance

    Jack Corbett (8/24/2011)


    Well, still working on it. Added an index and that took 15% off.

    The real winner is disabling and then re-enabling the FK's. There are 48 FK's...

  • RE: Keep Data Forever

    Keeping data forever?

    There are a few challenges:

    Physical locations fail.

    Media fails catastrophically (crashes). Try to keep it on two _different_ forms of media, at least one of which should not...

  • RE: Fastest 4 way Database Server

    I meant 16GB/s RAM bandwidth (2 million pages/sec * 8KB/page).

    Take a look at the Intel E7-4870 and E7-8837, both of which have a "turbo" frequency of 2.8Ghz when the workload...

  • RE: Fastest 4 way Database Server

    If you're only having issues after 16GB/s of throughput, you're in rarefied air already. You'll need to focus on RAM architecture, memory timings (critical), and bandwidth settings more than...

  • RE: DBCC UPDATEUSAGE

    GilaMonster (8/17/2011)


    DBCC UpdateUsage fixes page space information, nothing else. There were bugs in the the page space tracking algorithms on SQL 2000 and before, hence it was necessary to run...

    The cleanest install is always starting with a fresh OS and working up from there. I like Windows Server 2008 R2, even...

  • RE: Upgrading SQL Server 2000 to 2005. Best practice for a tidy install.

    The cleanest install is always starting with a fresh OS and working up from there. I like Windows Server 2008 R2, even as a host of SQL Server 2005.

  • RE: Going Big with SSDs

    clubbavich (8/16/2011)


    I hate to nitpick but I don't believe that many are using SSD's for their logfiles. The main performance advantage of an SSD is IOPS. 15k RPM drives aren't...

  • RE: Do DBA admins rather restore whole databases then restoring individual tables?

    From what I've heard, Virtual Restore is probably the easiest way to go.

    Aside from backups, there's archiving.

    I feel obligated to point out that for some situations, particularly where detailed change...

  • RE: Time for a ROWID?

    Eric M Russell (7/27/2011)


    How would you leverage ROWID for detecting "overlapping date ranges"; doesn't that typically involve comparing two or more date columns?

    It's the trivial case of "exclude each row...

  • RE: Time for a ROWID?

    Eric M Russell (7/27/2011)


    Nadrek (7/27/2011)


    I'd say stick with the simple; something very like a BIGINT IDENTITY on the table, not preserved after a table drop or truncate. Preferably one...

  • RE: RAID 10, Crystal Disk Mark Weird score?

    stebennettsjb (7/25/2011)


    Hi all,

    Ive been using SQLIO to compare my hard drives but decided to try out Crystal Disk Mark as its so much quicker.

    Go back to SQLIO, particularly using...

  • RE: Time for a ROWID?

    Eric M Russell (7/27/2011)


    When a table is edited in SSMS, say to add a column or alter it's datatype, the operation will often times be scripted out in the form...

  • RE: Time for a ROWID?

    Steve Jones - SSC Editor (7/27/2011)


    Eric M Russell (7/27/2011)


    I'm just thinking that, if the page size is 256K or 1MB, then how would that impact page splits and logical fragmentation...
