Hello Ricardo,

If you have many columns, the export will take considerable amount of time even with just 1000 rows.
Other factors that could slow down the process (besides the rows count) are:
- hierarchy
- template columns with complex structure

I recommend that you try the ExcelML (faster in some scenarios) or CSV (fastest) export.
