If you insist: why is bash so slow?  YOU could brush YOUR tooth while 
waiting for that slug to finish.


On my Win11 AMD 5600G machine, to create and delete 100K files:

WSL Ubuntu bash: 141.2s create,  1.4s delete, 142.6 total (your script)
PowerShell     :  21.2s create, 10.5s delete,  31.7 total
Python + cmd   :  16.6s create,  6.7s delete,  23.3 total

ouch!


PowerShell
-------------------------------------------------------------------------
PS D:\temp> md temp_txt
PS D:\temp> cd temp_txt
PS D:\temp\temp_txt> Measure-Command {for($i=1;$i -le 
100000;$i++){New-Item "file$i.txt" -ItemType File}}
TotalSeconds      : 21.1754938

PS D:\temp\temp_txt> cd..
PS D:\temp> Measure-Command { Remove-Item -Recurse -Force "temp_txt\" }
TotalSeconds      : 10.5104128
-------------------------------------------------------------------------
Total: 32 seconds



Windows Python and Windows cmd
-------------------------------------------------------------------------
D:\temp$ md temp_txt

for n in range(100000):
     with open('D:\\temp\\temp_txt\\file_' + str(n) + '.txt', 'w') as f:
         f.write(str(n))

D:\temp$ ptime python createfiles.py
16.648 seconds

D:\temp$ ptime rd /s /q "temp_txt"
6.705 seconds
-------------------------------------------------------------------------
Total: 23 seconds

Linux generally can't beat Windows fairly, because it's always been 
given away for free.  That's how it killed off Unix.

Linux cannot compete when people have a choice of what to buy and use.
