I have this workbench in which I combine multiple CSV-files and write out to one Excel-file. the file contains aprox. 190K rows. In the previous FME version (2020.x) I used this workbench it took a few minutes. Now the XLSXW is taking hours to write the output.
Did something change in the way the XLSXW writer functions? I did a test by writing to a CSV file, this took seconds to complete, so clearly the problem lies with the Excel writer.
Hopefully someone knows about a fix.
Cheers,
Jaap
