magento2 delay command bin magento

[Woshka]

Hello,

I have a magento2 installation that has a ~2 delays before processing any requests even from web or command

for example when I issue bin/magento I get repsonse for 2~3 seconds delay

 I removed all the modules and the themes setup:upgrade

compiled

deplyed static files 

removed /var/cache di and generation

but the problem still stays

the other magent2 installations have no problems

Are the other Magento installs on the same server or different servers?

Are you running this command via SSH or another method?

Have you checked your network connection on your server is healthy and you also have a good connection to the server?

If you run the bin/magento tool, all commands are instanciated during command registration.
This means that, if you run a single command, other commands can slow down yours.
Is there any 3rd party command installed by an extension. Sometimes a constructor argument opens resources. It can be fixed by changing them to a "Proxy".

I removed any third party extensions even by composer or in app/code but still it was about 4 seconds delay

even the whole website and admin panel also had this delay

after struggling a lot I had to reinstall and insert all products again

Please provide me instructions to trace this issue in the future to find out where it has such delay

Thanks

today I installed a clean magento 2.3.1 installation

it had no issues

I upgraded it using composer update and after the update there is 4~6 sec delay starting the command

./magento itself without any parameter has this issue

the following is the list of updates
