Performance on Windows 2003

  • We have 2 servers, both 2-processor Xeon machines with 2Gb of ram.

    Both servers have Windows 2003 Enterprise installed on it.

    Machine A is our application server and machine B is the database server holding an installation of SQL Server 2000 Enterprise.

    When executing queries from A to B with Query analyzer, or from our application, it takes approx. 5-10 seconds before we get a result.

    When replacing machine A with a Windows 2000 Server, the queries are executed 10-100 times faster.

    Are there any known issues regarding this problem ?

    Thanks in advance

    btw, Network performance is a non-issue, it has a GB network.

  • My experience is that there are 2 most likely possibilities:

    1) The W2003 DB server is very badly tuned and is running slowly.  This is unlikely, unless your site has done some serious tinkering with Windows default settings.  However, it is worth checking how much memory SQL is allowed to use (via EM) and making sure there is enough left for W2003. Remember that W2003 needs a good 100MB more than W2000 to run smoothly.

    2) The network card in one or both W2003 servers have not been set up correctly.  Get your network people to check duplex and packet size settings, and make sure they match the settings on the routers and firewalls, etc.  We have had some horrendous performance problems on various NT4, W2000, W2003 servers because these have not been set correctly.

  • Thanks for the reply ... our people are busy tuning the network ... we discovered that pinging took also too long

    It is obviously a network configuration problem

  • I always blame the network
