erpnext and frappe version 13 on Ubuntu 22.04.2 LTS

and I have more than 20 sites multi tenant

inside erpnext all operation work quickly but when user login in frappe ، The response comes after more than a minute

in database write command SHOW PROCESSLIST;
I see this command in process

SELECT table_name name,table_rows count FROM information_schema.tables;

and result come after 2 mins

What is the reason of this problem ?
