Heavy CPU usage while waiting for input in PowerShell
H0R5E opened this issue · 5 comments
Hi,
I noticed that when python-inquirer is waiting for input it is using a lot of CPU (probably a whole CPU thread) while waiting for input. I took these screenshots below:
The version I am running is:
inquirer 2.7.0 py_0 conda-forge
It's in a conda environment being run in PowerShell on Windows 10 Pro.
Is this expected behaviour? Is there anyway to make it less hungry?
Many thanks,
Mat
this comes from the underlying readchar libary which has a while: True loop in the windows implimentation. This is whats hogging all the CPU. (see magmax/python-readchar#42)
The new v4.0.0 fixes this but is only in pre-release right now. You can however test if it solves this issue if you want.
Sure, I'll give it a try.
than use this to update your readchar version:
pip install -U --pre readchar
Solved! Looking forward to the full release.
closed with the latest readchar release
