    I couldn’t understand what you mean by “so my question is how improve this reading seques 3500 to 100000 this count”. Can you be more clear?

    Regarding memory, you can (and should) configure how the cache works on your lookup component. You can set it to none, full or partial.

    • Full: runs the lookup query once
    • Partial: runs the lookup query once per ID and keeps the value
    • None: runs the lookup query every time. It keeps the last value in
      memory so if two equal values exist in 2 subsequent rows, it won’t
      run again

    and on full and partial you can configure the amount of memory used for the cache
