Very slow oryx build with python

Bug Report

I've noticed over the last few months, across all my web app pipelines, the build times have increased significantly for python applications. What used to be around 5 minutes now takes 20 minutes. Even very simple applications with very small requirement files take a long time to build. I am using ADO task: AzureRmWebAppDeployment@4 task to deploy. I am using zip deployment with webapplinux os. Scm_do_build_during_drployment is true.

When I look into the logs, it appears to hang at pip install.
