Is there any bottle neck which is causing the client write waits on
postgresql?
Sounds like a question for PostgreSQL.
Below is the test setup
Jmeter-->(load balanced tomcat on ec2 instances)---->rds read replicas
All these are running on different ec2 instances in AWS cloud in the
same region
below is the config of the http connector on tomcat:
<Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
connectionTimeout="120000" maxThreads="50000"
maxConnections="50000"
URIEncoding="UTF-8"
redirectPort="8443" />
That's a LOT of threads.
Below are the specs of the server:
Ec2 instance which is running tomcat 8.5
c5.9x large
36 vpcu
72GB memory
10GBPS network
EBS band width 9500
That's a lot of CPUs. I'm curious as to what you're doing with all that.
postgresql RDS db.r6g.16xlarge
512 GB memory
64 VCPU
25 Gibs network
AWS Gravitron cpu
