Choco install heavy archive issue

Hello,

I want to install a portable 5go software, this archive is stored internally.
The installation takes place correctly, choco downloads the zip, decompresses it and installs it via Install-ChocolateyZipPackage.
During the uninstallation I have trouble configuring something, it takes a lot of time. I have the impression that it makes a backup in lib-bkp, checks the md5sum of each file and then deletes the software in lib-bkp and lib. Uninstallation takes 5 times longer than the original uninstall exe. Is this normal?

Thx in advance

Start by reproducing the install and uninstall flow described with Install-ChocolateyZipPackage, paying attention to lib-bkp and lib and comparing the timings. The issue does not name a source file or test; done would require identifying whether the archive backup and checksum work is expected and documenting or correcting the slow behavior.
