    just as a side note, I can see your server is on Service pack 4, there are additional upgrades you might want to do.

    Regarding your question.

    WRITELOG

    This waittype indicates that the SPID is waiting for a transaction log I/O request to complete. This waittype may also indicate a possible disk bottleneck.

    you have a lot of

    CXPACKET

    These waittypes are all involved in parallel query execution. These waittypes indicate that the SPID is waiting on a parallel process to complete or start.

    I would check this activity and see what it is doing, hard to guess without knowing what else is going on, you might have a sp which does parallel queries perhaps.

    Put profiler on and have a look if you can.

  • You should evaluate Wait Stats. Andrew Kelly had an excellent little article in SQL Server Magazine recently. The Instanct Doc ID was 102111.
