+<p>SXSSF flushes sheet data in temporary files (a temp file per sheet) and the size of these temporary files
+can grow to a very large value. For example, for a 20 MB csv data the size of the temp xml becomes more than a gigabyte.
+If the size of the temp files is an issue, you can tell SXSSF to use gzip compression:
