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

Just for clarification: are you running Windows and Android on the same hardware in this example?

Sry, I should state my device model in the post

It's not just about storage speed. It's also about the CPU.

Smartphone hardware is generally noticeably weaker than laptop (let alone desktop) hardware.

There is not much you can do about this.
