    Actually, partitioning came sometimes accidentally (or coincidentally) help performance.  For example, the data was originally clustered by id, but to partition you cluster it first by a date.  IF you...

  • Reply To: Data Archival: 1 table (Database A) to 1 table (Database B)

    You don't really need to partition, assuming you re-cluster, although you could.  What will happen is that you will partition on date, so you will have to add date to...

    If avol is actually numeric.  If it's varchar, could be an issue.

  • Reply To: Data Archival: 1 table (Database A) to 1 table (Database B)

    Cluster both tables by ( StartDateTime, ID ) rather than just ID.  Then, since you'll be moving data in cluster key order, you can just use a standard copy-then-delete approach.

  • Reply To: Slow update on temp table

    Another possibility is, assuming that:

    (1) column avol was NULL before this UPDATE

    (2) your server still has the default FILLFACTOR 0f 0 (=100)

    Then this UPDATE could a lot of leaf page...

    Creating and dropping tables is significant overhead.  You'd be much better of, as others have noted, with a permanent table.  You could key rows in that table by user id...
