@mcn It's a bit difficult to help or comment with zero details from your side. What LibreOffice version, on what operating system? In what format is the spreadsheet? Help us to help you 😉
@libreoffice Simple spreadsheet with few thousand rows. LibreCalc takes about 2GB of RAM and is slugish while Excel takes about 95 MB and works like a charm. 😭
@mcn Can you provide the actual version number of LibreOffice? Also, .xlsx is Microsoft's format. If you save the file in LibreOffice's format (the open and standardised ODF, so .ods) then close LibreOffice and open the .ods, is there a difference?
@libreoffice Version 24.2.7.2 is a little bit better - only 1GB of RAM, even with ods file. It is really sad that in comparision to Excel, overall responsivnes is unacceptable in real business environment ☹️
