Issue/Introduction

Portal server for Classic Env , where there are 64 Gateway servers in 2 Datacenters (32 in DataCenter1 and 32 in Datacenter2).

Current resources of Portal Server are 32GB Ram, 8 vCPU & 500gb HDD.

Recently added a lot of Gateway servers in the capacity which has increased the resouce utilization on Portal server as well.

Currently Portal server Average CPU utilization is at 76% and Average memory utilization at 81%.

Can you please let us know the recommendations if we need to increase the resouces on Portal Server ?

Environment

Release : 4.5, 5.0

2. In order to do this, Portal DB must be externalized if you are using the OOTB Postgres DB.
