i have a web app which is hosted in EB and working perfectly but i notice that whenever the users on the website are getting larger or the requests are getting larger the websites slows and even run to Gateway Timeout in fron-end and also Target.Timeout in the instance heath but when the requests on the website or the users on the website get low againn the website will load faster.

i have change my Database instance type to db.t3.medium but stiill use to have more upto 99% usage when the website is slow.

the EC2 on the EB is running on t3.micro
