Hi Hackers,

One of the dependencies of cheroot - jaraco.functools was released on 20th Dec (v 3.0.0) which removed the support below Python 3.6. So while installing cheroot (using pgAdmin wheel) on Python 3.5, it is failing. cheroot works fine with its previous version of jaraco.functools==2.0.0. I've raised the issue to cheroot - https://github.com/cherrypy/cheroot/issues/258.
Please note, installers work fine as they are shipped with Python 3.7 venv. Ref - https://www.postgresql.org/ftp/pgadmin/pgadmin4/snapshots/2019-12-24/
Attached is the patch to pin jaraco.functools to 2.0.0 in requirements so that it does not fail below Python 3.6.

Hi Ashesh,

I had tried with - https://newrelic.com/ API to check Flask app performance. To be honest, there was not a great difference in the performance. 
Per new relic, cheroot used slightly less CPU, with more RPM and, with less response time.
Anyway, flask is still not recommended and cheroot looks a good option as it is pure python and supports almost all OS.

Have you seen any improvements in performance?

Hi Hackers,

Attached is the patch to use https://pypi.org/project/cheroot/ instead of current flask dev server. cheroot is a stable production ready server. Plus, flask dev server is not recommended for production.
Code is changed to use cheroot only when DEBUG is False, otherwise you the default flask server.

Kindly review.
