    Why freetext query become very slow all of a sudden


    Env: MS SQL Server 2005 developer edition on Windows XP Pro

    I have a fairly complex query that create a 'variable TABLE' and then,
    run a set of freetext search using the CONTAINS predicate,
    and add matches to this table;
    and then fetch the matches from the target table.

    The execution used to be 1/3 or 1/4 or even less of a second. But
    now, all of a sudden, it almost takes 1 second to run it. Nothing
    really has changed, be it, the db server, the db or the box itself.
    How come? I'm puzzled.
    Digging the log files, I found the following entry,
    "04/17/2008 03:49:26,spid1s ,Unknown,A significant part of sql server
    process memory has been paged out. This may result in a performance
    degradation. Duration: 374427 seconds. Working set (KB): 8028<c/>
    committed (KB): 24288<c/memory utilization: 33%.
    ", wtf? I mean, how come?

    I ran some similar queries using a query client, speed seems very
    good...

    Also, could it be caused by some Windows XP automatic update?
    (unintended consequence)
    Also, I'm using a third party tool for the web presentation, could
    some of its service degrade because previously it was good?

    Thanks.
Working...
