Hi,

We have a network setup with a vista server and an xp work station. We are running an application that reads a file open for input and then prints the data to file on disk. The application is extremely fast when run off the server - takes 1 minute to process 33000 records. The same application when run off the workstation across the network takes 35 minutes to process the records.
Does anyone have any ideas on what could be causing this ? We have tried with a 7.2 runtime as well as a 8.1.3 runtime - same problem.

Thanks

Med

    "The same application when run off the workstation across the network takes 35 minutes to process the records. "

    What do you mean "across the network" to run your application?
    Could you give more details about how your application run through the network?

    Our programs and data reside on the server. We can run the application on the server which take approx a minute or we can run it on the workstation which connects to the server (across a network). This takes approx 35 minutes to run the same application.
    Hope I have explained myself more clearly.

    Thanks

    It looks more likely time consums on file I-O acroos a network.
    Is it possilbe to adjust your application to save your file on your workstation which you run your application(or say change the file direcotry) to confirm the above my suspection.

    It is likely Windows Opportunistic Locking that is affecting performance.

    Try adding this to your Runtime configuration file:

    NT_OPP_LOCK_STATUS FAST
