why is unzipping on android so slow compared to Windows? I've tried ZipXtract, MaterialFile... All took 10+minutes to unizip a zip file that only took 30 seconds to unzip on Windows.

Why is this the case and i s there any way to speed it up?

Thanks a lot

EDIT:

I am using google pixel 9a so this issue looks like it might not be the issue of storage speed

Windows is not running in a virtual machine, just a normal laptop

Typo in the post fixed

EDIT AGAIN:

Solved!

yes it the archive does contains thousands of small files! I think that could be the reason of low performance on android mobile!

thanks a lot @Brett@feddit.org

I also use ZArchiver and unzipping is zippy (sorry) in my experience. Not quite as fast as Linux but that's to be expected considering the hardware difference.

However Windows is quite slow in this regard in my experience. It can easily take 30 seconds to extract a zip file that Linux can do in under a second, often with a sub 1MBps throughput. This is on an NVMe SSD.
