We recently switch out hosting from one AWS system to another one (switch the region from Asia to US-east).
The old system is very different from the current one. The old system is one EC2 instances that hosted multiple website and configure using cpanel.
This new one is having a load balancer that round robin between two instances and the websites files are hosted on a Network File System (EFS in Amazon). Instances are also connected to a Relationtional Database.
Once we switch over the hosting of one of the website to the new system. The site now takes a very long time to load (20-60+ seconds). I tried to optimize the page as much as possible (through google page insight), but the load time still takes forever.
I’m not sure how i can fix this issue.
I very new to server administration, so this is all very new to me.
Any advice on how I can go tackle this situation would be very helpful.
Thanks in advance.
