Magento 2 POS terminal is too slow on Magento 2.4.7

After we updated Magento to the latest version POS terminal started working too slowly. Is it a known issue?

Magento 2.4.7 uses the GraphQl endpoints in various processes. Our Magento 2 POS correspondingly relies on those endpoints in certain tasks too. 

However, Magento 2.4.7 and higher are known to have a problem with these endpoints being loaded for too long. Here is the reference: magento/magento2#38668.

So, to fix this issue, navigate to the app/etc/env.php and change the 'use_lua' value to false like in:

'use_lua' => false
