Python build is incredibly slow when built with sudo, compared to building as root

[mdrgon1]

I have two builds of python 3.8.14 that should be very similar, one I ran pyenv install with sudo and the other I ran pyenv install after su -. The second build is perfectly fine, but the first is unusably slow, I'm really not sure why. I'm sshed into a SUSE Linux Enterprise Server 15 SP6 vm.

Build command for build 1:

sudo -E env PYTHON_CONFIGURE_OPTS='--enable-optimizations --with-lto' PYTHON_CFLAGS='-march=native -mtune=native' pyenv install --verbose 3.8.14

Build commands for build 2:

su -
env PYTHON_CONFIGURE_OPTS='--enable-optimizations --with-lto' PYTHON_CFLAGS='-march=native -mtune=native' pyenv install --verbose 3.8.14

provided the outputs of these commands under sudo_install.txt and root_install.txt
sudo_install.txt
root_install.txt

I timed some simple commands to illustrate, but the slower build is just generally unusable.

Timing for 'sudo' build:

$ time python -c 'print("hello")'
hello

real    0m3.702s
user    0m0.050s
sys     0m0.014s

$ time pip --version
pip 22.0.4 from /dfs/is/home/m346009/.local/lib/python3.8/site-packages/pip (python 3.8)

real    0m37.287s
user    0m0.483s
sys     0m0.132s

Timing for 'root' build

$ time python -c 'print("hello")'
hello

real    0m0.014s
user    0m0.010s
sys     0m0.004s

$ time pip --version
pip 22.0.4 from /root/.pyenv/versions/3.8.14/lib/python3.8/site-packages/pip (python 3.8)

real    0m0.434s
user    0m0.376s
sys     0m0.058s

You have manually updated Pip for system Python, and Pyenv installations use the same path for user site packages. We asked users and haven't received any meaningful feedback yet on what the desired behaviour is.

Uninstall the user-site Pip for the system Python and you should be okay.

problem looks like it's still persisting, I removed pip and the entire user-site installation of python at /dfs/is/home/m346009/.local/lib/python3.8 and reinstalled python 3.8 with pyenv. pyenv which pip now shows /dfs/is/home/m346009/.pyenv/versions/3.8.14/bin/pip but the performance is still about the same.

$  time pip --version
pip 22.0.4 from /dfs/is/home/m346009/.pyenv/versions/3.8.14/lib/python3.8/site-packages/pip (python 3.8)

real    0m28.572s
