ZipPackage still use much Jvm Heap

[danmaidesenling]

Hi,
My test case is a xlsx file which has 1,000,000 rows and 97M. I use below code to parse it.
return StreamingReader.builder() .rowCacheSize(50) .bufferSize(1024) .open(file); (currenct version is 2.1.0)
and the highest memory footprint is 387M, I analyse it using Jprofiler. It shows the ZipPackage object is the major key.
Is there anyway to avoid this or will enhance this next release ? (currenct version is 2.1.0),
Thanks in advance for your response
