Elastic Beanstalk server slows down whenever a instance is added or removed on auto-scaling (Python 3.8 running on 64bit Amazon Linux 2)

So we have recently uploaded a new enviornment for our product

We are using python 3.8

Elastic beanstalk is of application type

This is my Auto Scaling group configuration

These are myscaling triggers configuration

I can see there are few spikes from the monitoring but these things were happening before also, at then we were not facing this issue

Is there something that I am missing in my confiuration, beacuse we have used exactly same configuration before and it was working fine. We have just updgraded from python 3.6 to python 3.8

Any help would be appreciated.
