> STEPS TO REPRODUCE
> 1. Create a new spreadsheet
> 2. Load a big txt file with data on it
This is because of the high number of columns in this file. When importing into
a spreadsheet, the data is organized internally in "columns" and we need to
create a column object for every column in the file. This, the overhead around
this creation and also the high memory consumption after the import is what is
causing issues here and this is definitely something that we need to improve.
P.S.: on a side node, the import of this data into a matrix container (not
spreadsheet) is significantly faster and doesn't cause any issues. Though, the
plotting and analysis capabilities for matrix-like data are very poor at the
moment in LabPlot...
