2.126 FAQ-1128 What should I do if Origin becomes very slow when working on large dataset?

Last Update: 5/9/2022

If you have a large dataset in a project file (many workbooks or a worksheet contains many columns/rows), and those dataset columns contain sparklines (displayed or hidden), any worksheet based operation will lead to performance slowness or even unresponsive.

You can try the following to speed up the system.

Turn off Sparklines for Current Datasets

Run the following scripts to delete all sparkline graphs in the project.

StringArray sa;

doc -e P
	if (%H == "sparkline*")

int nn = sa.GetSize();
for (int ii=1; ii<=nn; ii++)
	win -c %(sa.GetAt(ii)$);

Turn off Sparkline for Operation Outputs

If the manipulation/analysis tool you use on current worksheet/workbook will create a large number of new worksheet/workbook, e.g. Split Worksheet tool, the system speed will become slow since the Sparkline is turned on by default.

To speed up, please turn off Sparklines in the operation dialog.
