Issue
We have upgraded 1.8 to 3.1.4. The CMS is deployed at AWS t2.micro (Amazon Linux) since 2017. After directly upgrading from 1.8 to 3.1.4 last week we are facing very slow responses and slow browsing on admin and user accounts. 1.8 was running perfectly since inception. The total screens attached are 10. Normally 2-3 screens are active at any given time. Can anyone suggest what might be the issue?
