>                 Key: ARROW-8983
>                 URL: https://issues.apache.org/jira/browse/ARROW-8983
>             Project: Apache Arrow
>          Issue Type: Bug
>    Affects Versions: 0.16.0, 0.17.0, 0.17.1
>            Reporter: Valentyn Tymofieiev
>            Priority: Minor
>
> It appears that 
>           python -m pip download --dest /tmp pyarrow==0.17.1 --no-binary :all:
> takes several minutes to execute. 
> There seems to be an increase in runtime starting from 0.16.0: on Python 2 
>      python -m pip download --dest /tmp pyarrow==0.15.1 --no-binary :all:
> appears to be somewhat faster, but the same command is still slow on Py3.
> The command is stuck for a while with "Installing build dependencies ... ", and increased CPU usage.
> The intent of this command is to download source tarball for a package and its dependencies.
> Some investigation was started on the mailing list: https://lists.apache.org/thread.html/r9baa48a9d1517834c285f0f238f29fcf54405cb7cf1e681314239d7f%40%3Cdev.arrow.apache.org%3E
