in thread processing slows way down

The fields for the user data are defined by my's at the top of the script. The data is read, falls into a while until end of file. In the while, the fields are interpreted, the table fields are formatted, the insert is done, repeat the while.

We are not perl whizzes. The extent of our perl knowledge is pretty much what I explained above. We pick up bits of new bits of code as we come across new situations.

The scope for what I described is through whole script because of the my's at the top of the script? I so, how could it be a scope issue?

Thank you for trying to help.

    how could it be a scope issue?

    Without seeing the code, there really is no way to tell where the problem might lie. That's why I offered the suggestion on how you could check the problem out.

    It could be that there is a leak in one of the components your using to access Oracle. The simple test there is to comment out the DB code within the loop and re-run the script. If that stops the memory growth, you know where to look. If it doesn't, you also know where.

    All of which is pure speculation until you perform the test to see if memory leakage is the cause of the slowdown.

    Another possibility is that you are misusing DBI. There have been examples of code here at PM where people have been preparing their statements each time around the loop, rather than once outside and then executing them inside.

    Again, without sight of the code, pure speculation.

      Ok, thank you BrowserUk.

      I will look into what you describe and try to get back here with what happened.
