2.36 FAQ-468 My Origin project file is very slow to work with. How can I improve this?

Last Update: 12/20/2018

If your project is slow to load, or Origin runs slowly while you have your project open, try the following:

  • If you have a large number of windows (especially graph windows) within a single Project Explorer folder, you can try moving some of them into subfolders. You can also hide windows. Open Project Explorer, select windows in the lower pane, right-click and Hide.
  • Sparklines are "thumbnail" graphs that can be displayed in the worksheet column. If you have a large project file with many workbooks, and those workbooks contain sparklines (displayed or hidden), your system may perform poorly or become unresponsive. For information, see How can I remove sparklines from an Origin project file (OPJ) that is very slow?
  • If you have a big project file that periodically freezes, this may be caused by the Autosave feature. To turn off Autosave, click Tools:Options, select the Open/Close tab and uncheck Autosave Unsaved Project (<20 MB) (see the above link for instructions on adjusting the threshold file size).
  • Try clearing the Results Log. You can open it from the View menu, or use Alt-2 key. Right-click and choose Clear All. Prior to Origin 8.6, logging for many functions was enabled by default when importing, and thus these entries could accumulate over time. If you are concerned about losing the Results Log content, copy content to a Notes window and save it with the project file.
  • Origin 2018 introduced a new Unicode-compliant project file type -- OPJU. If you have upgraded to a recent version of Origin and you have older project files of the OPJ file type, consider resaving the files to the new OPJU format as it can produce significantly smaller project file sizes and faster loading and saving times.
