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.
This is honestly surprising to me. Wouldn’t they charge wealthy people more because they could just suck up the higher prices?
