How SQL handles Cursors

  • I have 2 servers. The OS on both is the same 2003 Ent. SQL 2005 is 64 bit

    ENT on one with SP2 and 64GB of RAM and 32 bit Standard on the other with

    SP1. We are using a 3rd party application and the application builds its

    sql dynamically. Now here is the problem. The older 32 bit server run

    better and in tracing it seems that it handles cursors MUCH better then

    the newer server but only with this application. The vendor claims to know

    nothing, which they always do. Anyone have any ideas? Config options i can

    try? We are even not applying sp2 on the 32 bit server in hopes of not

    ruining a good thing but the application database must move to the newer

    database server. Thanks!

    If the bottleneck is on IO 64bit or 32 bit would not matter.
