High CPU usage on Ubuntu 22.04 WSL

[Wyzix33]

Describe the bug On a fresh Ubuntu 22.04 installed as a Windows Subsystem for Linux (WSL) i'm seeing

PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
814 root      20   0   34516  24624  10804 R 100.0   0.3   0:15.78 python3

for as long as the server is running

To Reproduce create a server.py file containing

from socketify import App
app = App()
router = app.router()
app.listen(
    8080,
    lambda config: print(
        "Listening on port http://localhost:%d now\n" % config.port),
)
app.run()

Expected behavior Normal CPU usage

Screenshots

Desktop (please complete the following information):

• OS: Ubuntu 22.04 installed as WSL

Additional context Python 3.10.6 socketify.py v0.0.17

PS on a normal installation of Ubuntu 22.04 it's OK

Never tried on WSL before. I will setup a dual boot here and try it, Thanks for reporting, this type of feedback is essential!

Also there is the same problem on colab

This is actually an event loop issue, will be solved in next release, basically we just need to call less the event loop when idle, the CPU at 100% is because is calling the event loop even when is not really needed (idle) This will not hurt performance when requests comes.

fixed on v0.0.19
