Node 2: m4.xlarge machine wit Jira Dc v8.2.0
RDS Database Node: db.m4.large instance of AWS with PostgreSQL Database.
JIRA & RMsis were running over HTTPS behind the proxy offered by AWS.
A series of graphs is displayed below which displays the behavior in the above-mentioned configuration. The numbers on X-axis denotes the number of concurrent users accessing the RMsis while the Y-axis represents the time in milliseconds requires to complete each operation.
