Import of Library is Slow

[sanssecours]

Description

Importing the Network class takes quite some amount of time depending on the platform and hardware. Below are some examples:

Linux NUC	MacBook Pro	Windows NUC
[email protected]/4.80GHz	M1 [email protected]/3.2GHz	[email protected]
Python 3.12.3	Python 3.12.4	Python 3.12.4
~ 2.0325 s	~ 0.987 s	~ 5.092 s

I used the following commands for the measurement:

• Linux/macOS: time python -c 'from mytoolit.can import Network'
• Windows: Measure-Command { python -c 'from mytoolit.can import Network' }

repeated each measurement four times and calculated the average time.

Looks like the biggest contributor (56.2 %) to the slow import time is the tables library. At least that is what I gathered after executing:

python3 -X importtime -c "from mytoolit.can import Network" 2> read.prof

and checking the result with Tuna:

on the Linux NUC.
