Additional Information

They have 3149 rows and 3270 fields. A compressed file geodatabase is a column-oriented data store. Each column is compressed as a column. But since there are more columns than there are rows, there’s not a lot of context for compression. So compression will result in a larger file. With many more rows or fewer columns, better compression would be seen.
