Comment 11 for bug 1871138

python 2.7 version took longer time than python 3 version, but the difference was just a couple of seconds.

What I can tell are:
- Using python3 improves the performance
- pyScss 1.3.7 (possible >=1.3.5) take more time but the difference is just a couple of seconds (2~4 secs)

I ran my tests on ubuntu 18.04 baremetal machines. If it depends on machine environments (container vs baremetal), I am not sure this is an issue tackled by the horizon team.

I am leaning to marking this as Invalid in horizon.
