Performance Issues when working with multi-tab Files

I am trying to build a cash flow with multiple tabs in the file. The file is not big about 400 kb. Now opening the files takes a long time ..almost 20-25 sec. Is this a known issue.

Converting the file from .gnumeric to xlsx or ods format increases the size to 3 MB :slight_smile:

Libreoffice seems to open the file under 10 secs on the same machine/environment.

I am on latest version 1.12.61 on OpenBSD on a laptop with 16g ram.

Thanks.
