Allocating Memory

The amount of memory to allocate depends on the application, as well as the size and complexity of the project.

Configuring memory in the DUG Launcher

Allocate memory
  1. Open the DUG Insight Launcher.
  2. Choose the application to configure.
    • SEG-Y Loader
    • DUG Insight
    • Data Manager
  3. Set the maximum amount of memory for that application
    • The most recently used value is chosen by default.
    • If you haven’t run Insight before, a sensible value is chosen automatically.
    • Choose a value from the list, or enter your own choice.


  • Leave 1-2 GB free for the Operating System.
  • Leave enough memory available for other software
  • A warning appears if the memory entered is more than is available on the machine.

SEG-Y Loader

The SEG-Y Loader converts SEG-Y files into Insight’s high-performance dugio format. It does not require much memory and around 1000 MB should be sufficient.

DUG Insight

In general, Insight runs better with more memory allocated. We recommend giving Insight as much as possible, leaving 10% (or 2GB, whichever is larger) available for other processes. e.g. if you have 16 GB total RAM (16,000 MB) in your machine, allocate up to 14,000 MB for Insight.

Insight carefully manages its use of memory to get the best results. Generally, it caches data that is displayed or recently accessed. When work is done on-the-fly, the results are kept in memory for reuse (as much as possible).  This one of the secrets to Insight's speed when working with huge regional 2D and 3D projects.
