@wakabayashi you talk about totally unrelated stuff: compare the speed of shops and the speed of installation - what we were talking here - is 2 differents things.
PrestaShop 1.7 is very fast to install thanks to the Unpacker, this is a feature TB didnt provide right now (or you know stuff I didnt), the extraction of thousand of files using FTP tool like filezilla is very long (30min to ... hours), and the unpacker have been provided to fix this issue.
Thank you for your understanding
