Python ZipFile Slow for big files, Need Alternatives

Question

I am using ZipFile in python to unzip a 6GB file. But it seems to be taking over 3hours to do so. I need to find a better alternative to fit within 20mins. Below is the code i have been working with which works perfectly fine but is very slow.

Python: 3.8.8

from zipfile import ZipFile
str_zipFile = 'C:\\Users\\Documents\\Test.zip'
str_pwd= '1234'

with ZipFile(str_zipFile) as zipObj:
    zipObj.extractall(pwd = bytes(str_pwd,'utf-8'))

Please suggest a faster method.

Quote from Python zipfile module doc:

Decryption is extremely slow as it is implemented in native Python rather than C.

To get better performance, you can invoke an external program like unzip or 7z
