  • 1.  UniVerse: Has anyone ever tuned OPTMEM?

    Continuing on my search for more information about some of the uvconfig settings and their possible real-world tuning outcomes...


    The OPTMEM setting reads as an important option that could contribute to the performance of all RetrieVe commands.

    The uvconfig section reads as:

    # OPTMEM - This is the amount of memory allocated
    # for the query optimizer's workspace. It is
    # specified in 1K units (1024 bytes).
    OPTMEM 64

    Has anyone ever changed this setting?
    If so, what setting was used and what impact does/did it have?


    Thanks

    UV 11.3 did change the default value for OPTMEM from 64 to 256, so there must be some value in having a larger workspace.
    Has anyone gone beyond 256 as a setting, I wonder?
