http.server start delay

[pastacolsugo]

I'm trying to use python http.server with the following command:

python -m http.server 8000

but I'm consistently waiting 30 seconds for it to start up.
I'm working on a MBP 15" 2017, MacOS X High Sierra 10.13.4.

I tried closing all applications, restarting the computer, resetting PRAM and SMC; tried upgrading to python 3.7 (from 3.6.4) [via homebrew] and it didn't help; I tried using python3 -m http.server, and finally uninstalled python 3 and tried python 2.7's

python -m SimpleHTTPServer

but again I got the same result.
Each try was timed using time python -m http.server and pressing ^C after starting. The ^C remained in the buffer until the server started.

Each time the output was something along the lines of

Output:
real	0m30.089s
user	0m0.040s
sys	0m0.035s

with user and sys going up to around 80-100ms and real to 30.120ms!
My other Express.js apps launch immediately on localhost.

I'm guessing there's a 30 seconds timeout or delay somewhere that gets triggered, but I don't know why and how to solve it! I really don't even know where to look.

(It's my first post here, I'm not sure if it's the right section!)

Hm, that's very odd. I just tried it but couldn't replicate your findings. Have you tried a different port?
