- python3-debian
- python27

Classic vs of-watchdog templates
The current version of OpenFaaS templates use the original watchdog which forks processes - a bit like CGI. The newer watchdog of-watchdog is more similar to fastCGI/HTTP and should be used for any benchmarking or performance testing along with one of the newer templates. Contact the project for more information.
