I can find the issue as you have mentioned. I simply open and re-save your XLSM file, it takes more time to perform the task. We need to investigate and look into it if we can enhance the performance a bit more.
I have logged a ticket with an id: CELLSNET-41142 for your issue. Once we have any update on it, we will let you know here.
We have looked into your issue and found that are are lots of invisible shapes in your file. Could you check why there are 12374 invisible shapes in the range
H10:H11?
We will improve the performance of saving the file, but we cannot improve the performance of reading the file soon.
New dll works a bitfaster (43 sec). Just to compare
I am sending a file containing the same data (12374 hidden objects) but only in
Office2003 .xls format. To open and save this object it takes just one second.
It looks like an Aspose deals with 2003 and 2010 format files in a different
way. Could you please improve the saving time if it is possible? This is very important for us.
Well, in the fix v7.3.2.4, as we mentioned we have only improved the performance regarding Saving. We will improve the performance of Reading but it may take some time. We will further look into it and once we have any update on it, we will let you know here.
Also, XLSX is an OOXML file fomat which is different than older XLS file format and we have to handle it accordingly, see the document for reference:
